Udo W. Pohl

Udo W. Pohl is a German physicist who was Professor at Technische Universität Berlin. His work on semiconductor physics focuses on quantum dots.

Education and career

Pohl studied physics at RWTH Aachen University, the Free University of Berlin, and Technische Universität Berlin, where he earned doctoral degree in 1988. His doctoral research involved optical spectroscopy of transition metal impurities in II-VI semiconductors.^[1]

In 1989, he became the group leader of the "Materials Lab" at the Institute of Solid State Physics at Technische Universität Berlin, which was later reorganized as the Center of Nanophotonics in 2004.^[2] His scientific work focuses particularly on the structural and optical properties of quantum dots based on II-VI^[3] and III-V^[4]^[5] compound semiconductors and their epitaxy.^[6] Using active GaAs-based III-V-quantum dots, novel devices such as lasers and single-photon emitters could be realised at the Institute of Solid State Physics with his involvement.^[7]

Pohl qualified as an assistant professor in 1999 with work on the epitaxy of semiconductors. In 2009, he was appointed adjunct professor of experimental physics at Technische Universität Berlin.^[8] Pohl is member of the German Physical Society and since 2017 serves as a co-editor of the Springer Series in Materials Science.^[9]

Publications

In 2013, Pohl published the textbook Epitaxy of Semiconductors.^[10] He co-authored the Handbook Semiconductor Physics with Karl Wolfgang Böer, which was first published in 2018.^[11]
