Director of Applied Physics, Professor of Physics
About
Professor Kurdak’s research is mainly in the area of mesoscopic physics. At low temperatures and in small length scales, quantum effects and the discrete nature of charge become increasingly important. Professor Kurdak studies various systems, such as semiconductor quantum dots, quantum point contacts, and systems of Au nanoparticles, where these effects play a key role. Professor Kurdak’s research also focuses on the study of electrical properties of low-dimensional electron systems. In addition to two-dimensional electrons systems formed in semiconductor heterostructures, his group studies surface conduction on topological insulators. Many of the samples used in these experiments are fabricated using standard semiconductor processing techniques including electron beam lithography and they are characterized by low temperature transport measurements at temperatures as low as 20 mK.
Professor Kurdak is an Alfred P. Sloan Research Fellow from the Alfred P. Sloan Foundation.
