Research Activities and Scientific Accomplishments The topic of my research work is investigation of transport, optical and thermally stimulated phenomena in semiconductors Si, GaAs, SiC, GaN other A2B6, A3B5 compounds and structures as well as polymer semiconductors. I have all in all 121 scientific publications. Many of them appeared in the international magazines and were presented at the international conferences. A number of my articles were published in the world - leading journals, e.g., The Physical Review B, Journal of Applied Physics, Applied Physics Letters, Journal de Physique and others. Our original investigation method of the transport and recombination phenomena is patented as an invention. I also have published two text-books. All in all I have spent more than three years working abroad at the well-known universities and research centres. The financial support for these academic and scientific projects was given by international state and private foundations, basing on the competitive ability of my scientific projects. I know well Lithuanian, English, German, and Russian languages, and have a basic knowledge of French and Polish languages. Some selected publications : V. Kaşukauskas, J. Grohs, C. Klingshirn, G.
