Publikováno v: IEEE Transactions on Terahertz Science and Technology. 5:659-664

We report on the influence of oxidation on features of surface electron states in PbSe films—materials belonging to the family of topological crystalline insulators Pb $_{1-x}$ Sn $_x$ Se. These states are detected through observation of the photoe

Publikováno v: JETP Letters. 104:68-70

It has been shown that a magnetic field in PbTe(Ga) single crystals induces the appearance of a positive photoresponse in the terahertz spectral range. Nonequilibrium charge carriers are generated from states located against the background of the con

Publikováno v: 2016 41st International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz).

In this work, we show that the use of terahertz laser radiation combined with magnetic field provides an opportunity to detect high mobility surface electron states in (Bi 1−x In x ) 2 Se 3 solid solutions being either in topological insulator (TI)

Publikováno v: Journal of Alloys and Compounds. 615:375-377

We report on unusual photoconductivity under the action of strong terahertz laser pulses in PbTe(Ga) single crystals at low temperatures. The character and even the sign on the photosignal depends on the level of photoexcitation: the photoconductivit

Terahertz probing of surface electron states in topological crystalline insulators Pb1−xSnxSe

Autor: Sergey Ganichev, Lada V. Yashina, E. P. Skipetrov, Sergey Danilov, Ludmila I. Ryabova, Dmitry Khokhlov, S. G. Egorova, V. I. Chernichkin

Publikováno v: 2015 40th International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz).

We suggest a method for detection of highly conductive surface electron states including topological ones. The method is based on measurements of the photoelectromagnetic effect using terahertz laser pulses. In contrast to conventional transport meas

Optimal conditions of protein scanning by atomic force microscopy were developed. Proteins of different molecular masses (950-11.5 kDa) and different three-dimensional organization were used to investigate the structural features of proteins. The mos
