[IEEE 2018 43rd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz2018) - Nagoya, Japan (2018.9.9-2018.9.14)] 2018 43rd International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz) - Effect of Magnetic Field on Terahertz Photoconductivity in Hg<inf>l-x</inf>Cd<inf>x</inf>Te-Based Structures

摘要： In this paper, we show that the positive terahertz photoconductivity in Hg1-xCdxTe solid solutions being in a topological phase (x < 0.16) strongly depends on the combination of both the external magnetic field direction and the potential probe position. The asymmetry in the photoresponse in the magnetic field may be due to the spin-related features of the carriers excited.
