Infrared Radiation Induced Gyrotropic Photocurrents in Semiconductor Nanostructures

摘要: This thesis deals with an advanced experimental investigation of infrared radiation induced gyrotropic photocurrents in semiconductor nanostructures. These provide access to non-equilibrium processes low-dimensional materials like quantum wells allowing especially studies spin and orbital properties carriers. Even though a noticeable progress both the basic research utilisation currents has been achieved, their complete understanding is still challenge. The conducted measurements improve knowledge by revealing number new phenomena. Among them are first observation circular photon drag effect demonstrating simultaneous transfer linear angular momenta carriers detection nonlinear magneto-gyrotropic photocurrent. latter coheres heavy-hole type lowest conduction band HgTe allowing, for instance, determination Hall insulator state.
