TITLE: Conducting Atomic Force Microscopy (C-AFM) at Statistically Relevant Scale for Rapid Assessment of Non-Volatile Memory Materials and Devices

SPEAKER: Dr. Kumar Virwani, Research Staff Member at the IBM Almaden Research Center

ABSTRACT:
Over the past few years we have investigated applications of Mixed-Ionic-Electronic–Conduction (MIEC) materials as access devices for various non-volatile memory candidates, including Resistive RAM (RRAM). In this talk we describe the role of conducting atomic force microscopy in the discovery of new mixed ionic electronic conductors, and in the optimization and monitoring of fabrication processes for both MIEC and RRAM devices. For more on Storage Class Memory at Almaden see this project page.

C-AFM measurements on MIEC and RRAM devices yield fast, reliable and statistically relevant information that can be applied towards the optimization of materials, electrodes, anneal conditions and a host of other parameters relevant for ultimate device performance. From an instrumentation perspective, we show how thousands of I-V (current vs. voltage) measurements can be both repeatable and reliable. We describe how to overcome C-AFM challenges such as set-up inconsistency, non-repeatable I-V performance, probe life and lack of large statistics.

Establishment of short-loop fabrication procedures allow devices to be delivered for C-AFM testing rapidly, allowing quick turnaround in the assessment of myriad processing choices. Yet by validating an exact subset of the full fabrication procedure needed for fully integrated devices, such short-loop devices also provide for maximal efficiency in yield learning. One-to-one correlations between data from automated probe testing and C-AFM measurements, and unique fabrication knowledge and extensive device scaling data obtained via C-AFM will be presented.

TITLE: Thermal Management At The Extremes

SPEAKER: Ken Goodson, Professor & Department Chair, Stanford University, Mechanical Engineering

ABSTRACT:
The semiconductor industry is pushing many technological boundaries, and this motivates thermal management research at extreme lengthscales, timescales, and power densities. At Stanford we are grappling with several related questions: Are there thermal scaling limits for nanotransistors below 10 nm? What exotic cooling methods are needed for highly integrated 3D chips and power electronics? Can we convert waste heat to electrical power for appliances, sensor arrays, and efficient vehicles?

This talk covers these challenges and describes the rapidly evolving thermal management toolset from picosecond lasers and submicron infrared imaging to Monte Carlo simulations that is helping to sort them out. The talk also highlights the enormous help we receive from semiconductor companies, in particular here in Silicon Valley.

TITLE: A Multiview Backlight for Mobile 3D Displays

SPEAKER: Dr. Zhen Peng, Research Scientist, HP Laboratories

ABSTRACT:
Multiview three-dimensional (3D) displays can project the correct perspectives of a 3D image in many spatial directions simultaneously. They provide a 3D stereoscopic experience to many viewers at the same time with full motion parallax and do not require special glasses or eye tracking. None of the leading multiview 3D solutions is particularly well suited to mobile devices (watches, mobile phones or tablets), which require the combination of a thin, portable form factor, a high spatial resolution and a wide full-parallax view zone (for short viewing distance from potentially steep angles). Our technology relies on the external modulation of a multidirectional backlight that allows the projection of independent images in hundreds of different spatial directions, allowing any number of viewers to experience the 3D stereo effect without the need for glasses and with a continuous sense of motion parallax in a very wide view zone, at an observation distance of up to a meter. The key to our design is a guided-wave illumination technique based on light-emitting diodes that produces wide-angle multiview images in color from a thin planar transparent lightguide. To illustrate the capabilities of this technology, we use simple ink masks or a high resolution commercial liquid-crystal display unit to demonstrate passive and active (30 frames per second) modulation of a 64-view backlight, producing 3D images with a spatial resolution of 88 pixels per inch and full-motion parallax in an unprecedented view zone of 90 degrees. We also present several transparent hand-held prototypes showing animated sequences of up to six different 200-view images at a resolution of 127 pixels per inch. The resulting display is power efficient, ultra-compact, low-cost and optionally transparent.

TITLE: Splitting One Photon to Two Electrons: Toward Breaking the Single Junction Efficiency Limit

SPEAKER: Dr. Jiye Lee, Postdoctoral fellow in the Molecular Foundry at LBNL

 

ABSTRACT:
Conventional solar cells generate one electron for each absorbed photon. Any excess photon energy above the bandgap is wasted as heat. This fundamental energy loss imposes the Shockley-Queisser limit of 34% for single optimized semiconductor junction. Singlet fission, a nanoscale process in organic molecules, splits a high-energy molecular excitation into a pair of low-energy ones. In solar cells, it promises to double the electricity generated from the blue part of the sunlight, breaking the single junction efficiency limit.

I will present fission-based photovoltaic cells that produce more than one electron per photon. This is the first time that any solar cell has shown the peak photon-to-electron conversion efficiency exceeding 100% in the visible spectrum. To further advance fission-enhanced solar cell nanotechnology, it is crucial to understand the fundamental mechanism governing singlet fission. I will report on a universal mechanism that predicts the rate of singlet fission and confirm that fission is robust to variations in molecular nano-morphology.

TITLE: Energy Harvesting from Waste Heat and Sun Light with Mesoscopic Materials

SPEAKER: Prof. Nobuhiko P. Kobayashi, Dept. of Electrical Engineering, UC Santa Cruz

 

ABSTRACT:
Designing solid-state devices is essentially restricted by choosing available chemical elements found on the Periodic Table and forming various stable solids made of these chemical elements. A key to developing novel solid-state devices is, therefore to find a route to combine a variety of such solids often physically and/or chemically incompatible each other to benefit from resulting combined material platforms. In this talk, specific examples of “Mesoscopic Materials” will be presented with the view toward solid-state devices for energy harvesting from waste heat and sun light. The talk is divided into the following two sections.
1. Semiconductor nanocomposites for energy harvesting from waste heat: thermoelectric.
2. Metal oxide thin films for high-power solar energy collection and transmission: Sun to fiber.

TITLE: Fiber SERS Sensors for Molecular Detection

SPEAKER: Dr. Claire Gu, Department of Electrical Engineering
University of California, Santa Cruz

 

ABSTRACT:
Optical fibers have been successfully used in long-haul communication systems, endoscopy, and other optical systems to transmit optical power as well as information. In integrated sensor systems, optical fibers have been frequently employed to connect the source and the detector, due to their flexibility, compactness, and low loss. However, optical fibers can provide more functionalities than a simple transmission channel.

In this talk, we review our work on various optical fibers as platforms for molecular sensing based on surface enhanced Raman scattering (SERS). The fibers serve to significantly increase the sensitivity of SERS and to facilitate the integration of a compact sensor system. Specifically, three types of fiber SERS probes have been able to enhance the sensitivity of detection beyond that of direct detection: 1) liquid core photonic crystal fiber (LCPCF), 2) tip-coated multimode fiber (TCMMF) in conjunction with a second SERS substrate mixed with the analyte solution, and 3) nanopillar array fabricated on the tip of a multimode fiber. Integration of such fiber probes with a portable Raman spectrometer brings the SERS detection one step closer to practical applications. In this talk, we will discuss the principle of operation of various building blocks, demonstrate our recent results, and highlight some potential applications.
