Distinguished Lecturer Talk Title: Spintronics, nanomagnetic computing

Abstract: The lectures will consist of various aspects of spintronics, including but not limited to spin-based computing, spin transport in nanostructures, spintronic sensors, spintronic photodetectors etc. Additionally, the lectures may address the burgeoning field of straintronics pioneered by the nominee and a colleague. Straintronics relates to reorienting the magnetization of shape anisotropic nanomagnets with mechanical strain generated by tiny electrical voltages. This effect can be exploited to implement nanomagnetic logic systems and memory with unprecedented energy efficiency.

Distinguished Lecturer Talk Titles:

1: Nanoimprinted polymeric and perovskite photovoltaics: effects of geometry on 3D chain alignment and performance enhancement.

2: Quantum confinement effects in top-down nanowire devices and application in ultrasensitive biosensing

Abstract, Talk 1: Nanostructure is the core enabling technology for future semiconductor manufacturing and emerging nanotechnology applications in renewable energy and medicine. For example, nanostructures of conjugated polymer has greatly enhanced the performance of organic photovoltaic devices (OPV). The performance of OPV is greatly determined by the nanoscale morphology of the donor/acceptor heterojunctions and the molecular orientation/crystallinity in the photoactive layer. A vertically bicontinuous and interdigitized heterojunction between donor and acceptor has been regarded as one of the ideal structures to enable both efficient charge separation and transport. In this talk, I will present our work of using nanoimprint lithography (NIL) as a new approach to simultaneously control both the heterojunction morphology and polymer chains in OPV. We found that nanoimprint procedure changes the initial edge-on alignment in non-imprinted P3HT to a vertical orientation which favors the hole transport, with an organization height over 170 nm and width in the range of 60- 210 nm. Better chain alignment improves hole mobility in P3HT nanogratings to be 0.03 cm2/Vs. It is also found that NIL enables stronger chain alignments in high molecular weight (MW) P3HT, showing its potential to release the benefits of high MW polymers that are not suitable for bulk heterojunction devices due to severe chain entanglement. These findings are further proved by increases in power conversion efficiency of OPVs using imprinted P3HT/PCBM nanostructures. Finally, I will show the initial results of using NIL to pattern perovskite nanostructures with improved crystallinity, which is very promising to further improve the performance of perovskite photovoltaics.

Distinguished Lecturer Talk Titles and Abstracts:

  1. Nanopackaging: Nanotechnologies for Microelectronics Packaging

Nanotechnologies offer a variety of materials options for reliability improvements in microelectronics packaging, primarily in the applications of nanoparticle composites, or in the exploitation of the superior properties of carbon nanotubes and graphene. Nanocomposite materials are studied for resistors, high-k dielectrics, electrically conductive adhesives, conductive “inks,” underfill fillers, and solder enhancements, while CNTs and graphene may also find thermal, interconnect, and shielding applications. The talk will focus on these materials technologies, with some discussion of nanoparticle and CNT properties, a brief “Introduction to Electronics Packaging,” and some cautionary remarks on EHS issues in nanotechnologies manufacturing.

  1. Electrical Properties in Discontinuous Metal Thin Films

The initial nucleation and growth process of ultrathin metal films on insulating substrates produces an array of discrete metal nanoparticle islands due to the weak metal-to-substrate adhesion. Despite the lack of metallic continuity, such films are electrically conductive due to electron tunneling across the nm-scale gaps between islands. Essentially the films consist of an array of coulomb blocks, and the energy required to charge an individual island gives rise to an electrostatic activation energy as in SET structures. The presentation will discuss the calculation of this energy, with relevance to SETs, and a variety of experimental properties with potential applications, leading to a conduction model which explains all these apparently contradictory observations.

  1. Nucleation and Growth of Ultrathin Metal Films

The discrete nanoparticle island structure of metal thin films on insulating materials, e.g. IC metal interconnect on SiO2, is predicted by classical thermodynamics. However, the numerical values involved require an atomistic treatment to predict some counter-intuitive observations. Both models will be reviewed in the presentation which will then focus on the effects of electrical charges on the process, effects typically neglected despite their dominance in controlling film structure and properties in real systems.

Note: Topics #2 and #3 can be combined on request.

Distinguished Lecturer Talk Title: Semiconductor Nanowires for Optoelectronics and Energy Applications

Abstract: Semiconductor Nanowires are considered as building blocks for the next generation electronics and photonics.  Nanowires due to their nanoscale dimensions alleviate issues of lattice mismatch and in principle allow one to grow nanowires of any material on any substrates. Two main growth methods are used to grow epitaxial nanowires, vapor liquid solid (VLS) growth mechanism using catalysts such as gold and selective area epitaxy.  This talk will cover how to growth nanowires and control their size, shape and composition including growth of heterostructures and quantum structures. This talk demonstrate excellent electronic and optical properties in a wide variety of III_V semiconductor nanowires including enhancing the light emission by using quantum well tubes and plasmonics. Optoelectronic devices such as nanowire lasers, nanowire solar cells and nanowire terahertz detectors will be discussed.  Future prospects of nanowires for optoelectronic device applications and photocatalysis will be discussed.

Distinguished Lecturer Talk Title: Carbon Nanotechnology Materials and Devices

Abstract: Many sp2 bonded or sp3 bonded nanoscale carbons exhibit unique and excellent physical and chemical properties for practical applications. Rapidly advancing synthesis, processing, fabrication, integration, and mass production technologies make nanoscale carbons available and affordable to broad scientific and industrial communities, while more new forms of nanoscale carbons are being discovered or synthesized in the laboratory.  Both amorphous, crystalline, and hybrid forms of nanoscale carbons have been proven to be scientific and technologically significant.  This lecture will emphasize on crystalline, including nanocrystalline and ultrananocrystalline nanoscale carbons and review innovative manufacturing technologies and applications of 0-D carbon quantum dots, 1-D carbon nanotube, 2-D graphene, 3-D nanodiamond, and hybrids based on them. Examples to be given include intrinsic and doped graphene and its derivatives as well as fullerene and carbon nanotube based innovative nanoelectronics and nanophotonics. Intrinsic and doped nanodiamond and ultrananocrystalline diamond providing combined excellent properties for electrochemical, electronic, optical, tribological and biomedical applications will also be addressed. Applications of hybrids of ultrananocrystalline diamond and sp2 bonded nanoscale carbons, for example, for lithium ion battery electrodes will be presented. Nanoscale carbons are multidisciplinary materials offering us abundant opportunities of a greater future.
