Digital Systems Seminar

HVDC – Connecting to the future

Wednesday, February 26, 2014; 11:15am-12:15pm; Evans Hall

 

Abstract:  The seminar will give a broad introduction to the development of High Voltage DC (HVDC) Transmission in power systems around the world, which has for many years been based on the thyristor as the semiconductor of choice. The newly introduced voltage source converter technology, based on the use of the IGBT transistor, has increased the range of potential applications, and removed many barriers to enable the more extensive use of HVDC. Further development work is ongoing in many areas to bring reduced cost, additional functionality, improved integration of renewable generation, and to build more intelligent power systems for the future.

Bio:  Neil Kirby joined Alstom Grid after graduating from the University of Newcastle-Upon-Tyne in England in 1982, and was initially based at the power electronics design center in Stafford, England. Neil has worked in many areas of HVDC projects, including the detailed design of control systems hardware and software, and more broad-based project engineering.  He has also worked on extended assignments on various HVDC project sites including UK, Canada, India, South Korea, carrying out commissioning work, and taking responsibility for overall system tests.  In 2003 Neil moved with his family to Philadelphia in the USA, and is presently Business Development Manager for the HVDC & FACTS business in N America.

NEP Seminar Series

Wannier-Stark Localization and THz Emission from SiC Natural Superlattices

Tuesday, August 26, 2014; 4:00-5:00pm; Evans Hall

 

Recent results of the study of intense THz emission from SiC structures with natural superlattices (NSL) in high electric fields will be presented and discussed. The set of experimental data allows the emission to be attributed to optical transitions of electrons between the Wannier-Stark ladder (WSL) states, which are formed in the NSL in high electric fields. Experimental data also suggest that due to specific properties of the SiC band structure, both intra-WSL and inter-WSL optical transitions can be observed in the THz emission at very high electric fields. The intense, linearly polarized THz electroluminescence with adjustable frequency could find applications for tunable THz emitters.

STEPHANIE LAW

NEP Seminar Series

Doped semiconductors for mid-infrared plasmonics

Tuesday, September 2, 2014; 4:00-5:00pm; Evans Hall

 

Abstract: The fields of plasmonics and metamaterials have seen significant growth in recent years, due to the interest in confining light to subwavelength volumes both for fundamental physics studies as well as novel device architectures. Much of this work has been done in the visible spectral range with traditional metals such as gold and silver. In this talk, I will discuss my recent work using new materials, specifically heavily-doped InAs grown by molecular beam epitaxy, for infrared plasmonic devices. I will explain the advantages of these new materials over traditional plasmonic materials in the infrared and demonstrate that they act as near-perfect Drude metals with tunable optical properties which can also be integrated with existing semiconductor optoelectronic devices. I will then demonstrate the utility of such materials in the fabrication of nanoantennas, which allow for confinement of the electric field in nano-scale volumes and thus enhanced interaction of long-wavelength infrared light with nano scale particles. I will close by discussing some recent work using other semiconductor materials.

 

Bio: Dr. Law received her B.S. in Physics from Iowa State University and her Ph.D. in Physics from the University of Illinois Urbana Champaign, where she studied interactions between superconductors and semiconductors.  She then held a postdoctoral position in the Electrical Engineering department at Illinois where she demonstrated the feasibility of using doped semiconductors as tunable, low-loss infrared plasmonic materials.  She is currently the Clare Boothe Luce Assistant Professor in Materials Science and Engineering at the University of Delaware.  Her research investigates the use of novel materials and architectures for plasmonic and metamaterial devices in the infrared and THz.
