Effect of Magnetic Field on Terahertz Photoconductivity in Hgl-xCdxTe-Based Structures

In this paper, we show that the positive terahertz photoconductivity in Hg

Te 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.
