Thermoelectric transport in two-dimensional topological insulator state based on HgTe quantum well
G. M. Gusev, O. E. Raichev, E. B. Olshanetsky +4
The thermoelectric response of HgTe quantum wells in the state of two-dimensional topological insulator (2D TI) has been studied experimentally. Ambipolar thermopower, typical for…
Thermopower of a Two-Dimensional Semimetal in a HgTe Quantum Well
E. B. Olshanetsky, Z. D. Kvon, M. V. Entin +4
The thermopower in a two-dimensional semimetal existing in HgTe quantum wells 18-21 nm thick has been studied experimentally and theoretically for the first time. It has been found…
Microwave absorption in a 2D topological insulators with a developed network of edge states
M. M. Mahmoodian, M. V. Entin
The 2D HgTe quantum well is analyzed based on the assumption that the width fluctuations convert the system to a random mixture of domains with positive and negative energy gaps. T…
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…
Optical Transistor for an Amplification of Radiation in a Broadband THz Domain
Kristian Hauser A. Villegas, Fedor V. Kusmartsev, Y. Luo +1
We propose a new type of optical transistor for a broadband amplification of THz radiation. It is made of a graphene--superconductor hybrid, where electrons and Cooper pairs couple…
Atomic and electronic structure of the Si(331)-(121) surface
Ruslan Zhachuk, José Coutinho, Krisztián Palotás
We report on the investigation of the atomic and electronic structures of a clean Si(331)-(121) surface using a first-principles approach with both plane wave and strictly…
