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…
Unconventional Reentrant Quantum Hall Effect in a HgTe/CdHgTe Double Quantum Well
M. V. Yakunin, S. S. Krishtopenko, S. M. Podgornykh +7
We report on observation of an unconventional structure of the quantum Hall effect (QHE) in a -type HgTe/CdHgTe double quantum well (DQW) consisting of two HgTe lay…
Perspectives of HgTe Topological Insulators for Quantum Hall Metrology
Ivan Yahniuk, Sergey S. Krishtopenko, Grzegorz Grabecki +16
We report the studies of high-quality HgTe/(Cd,Hg)Te quantum wells (QWs) with a width close to the critical one , corresponding to the topological phase transition and graphen…
Spin splitting of surface states in HgTe quantum wells
A. A. Dobretsova, Z. D. Kvon, S. S. Krishtopenko +2
We report on beating appearance in Shubnikov-de Haas oscillations in conduction band of 18-22nm HgTe quantum wells under applied top-gate voltage. Analysis of the beatings reveals…
Sign-alternating photoconductivity and magnetoresistance oscillations induced by terahertz radiation in HgTe quantum wells
M. Otteneder, I. A. Dmitriev, S. Candussio +7
We report on the observation of terahertz radiation induced photoconductivity and of terahertz analog of the microwave-induced resistance oscillations (MIRO) in HgTe-based quantum…
