Terahertz photoresistivity of a high-mobility 3D topological insulator based on a strained HgTe film
M. L. Savchenko, M. Otteneder, I. A. Dmitriev +3
We report on a detailed study of the terahertz (THz) photoresistivity in a strained HgTe three-dimensional topological insulator (3D TI) for all Fermi level positions: inside the c…
Symmetry breaking and circular photogalvanic effect in epitaxial CdHgTe films
S. Hubmann, G. V. Budkin, M. Otteneder +13
We report on the observation of symmetry breaking and the circular photogalvanic effect in CdHgTe alloys. We demonstrate that irradiation of bulk epitaxial films with c…
Cyclotron resonance induced photogalvanic effect in surface states of 200 nm thick strained HgTe films
S. Candussio, G. V. Budkin, M. Otteneder +7
We report on the study of magneto-photogalvanic and magnetotransport phenomena in 200 nm partially strained HgTe films. This thickness is slightly larger than the estimated critica…
High frequency impact ionization and nonlinearity of photocurrent induced by intense terahertz radiation in HgTe-based quantum well structures
S. Hubmann, G. V. Budkin, A. P. Dmitriev +10
We report on a strong nonlinear behavior of the photogalvanics and photoconductivity under excitation of HgTe quantum wells (QWs) by intense terahertz (THz) radiation. The increasi…
