| Abstract: There exists an urgent need to realize sensitive infrared photodetectors for application in military and civilian sensing. An innovative approach to realizing these devices is to employ a structure with quantum dots surrounded by repulsive potential barriers created using interdot doping. Spatial separation of the localized ground state and continuum conducting states of the electron increases significantly the photoelectron capture time and photoconductive gain. Large value of the gain results in high responsivity, which in turn improves detectivity and raises the device operating temperature. The work was done in collaboration with V. Pipa, A. Sergeev, and M. Stroscio. |
| Biography: Vladimir Mitin received his Candidate (1971) and Doctor (1987) of Physical and Mathematical Sciences degrees from the Institute of Semiconductors of the Ukrainian Academy of Sciences in Kiev. Currently he is a Professor of Electrical and Computer Engineering at Wayne State University, Detroit, Michigan. Since joining this University in 1989, he graduated ten Ph.D. students and four MS students. Dr. Mitin is a specialist in electronic and optoelectronic materials and devices. Currently he is working in the following areas: design and simulation of optoelectronic and microelectronic devices; heat dissipation in nano-structure and nano-devices; light absorption and emission in inhomogeneous materials, heterostructures, and nanostructures. Special emphasis in his research now is in simulation and modeling of high-speed multi-terminal lasers, terahertz generators, and quantum dot infrared photodetectors. As a result of his research and teaching activity he co-authored more than 350 professional publications including 10 patents, more than 150 publications in refereed journals, and more than 180 publications in conference proceedings and papers presented at conferences. He has co-authored three textbook and four monographs. |
