Ultrafast lattice and electron dynamics induced in a PbSe crystal by an intense terahertz pulse

A. A. Melnikov, Yu. G. Selivanov, D. G. Poydashev +1

We have studied the ultrafast optical response of a PbSe crystal to an intense picosecond terahertz pulse with a peak electric field strength of up to 500 kV/cm. The reflect…

Terahertz electro-optic effect in BiSe crystals

A. A. Melnikov, A. A. Sokolik, Yu. G. Selivanov +1

We report the observation of the electro-optic effect in BiSe crystals induced by an intense single-cycle terahertz pulse. The effect reveals itself as a transient change o…

Anharmonic coherent dynamics of the soft phonon mode of a PbTe crystal

A. A. Melnikov, Yu. G. Selivanov, S. V. Chekalin

We investigate the ultrafast optical response of PbTe to an intense single-cycle terahertz pulse, resonant with the soft transverse optical (TO) phonon mode of the crystal. We dete…

Anomalous behavior of the infrared-active phonon mode in a BiSrSe crystal

A. A. Melnikov, K. N. Boldyrev, Yu. G. Selivanov +1

We have studied spectral evolution of the phonon line of a topological insulator BiSrSe with temperature. Unlike the Raman-active phonons, the mode…

Phonon-driven ultrafast symmetry lowering in a BiSe crystal

A. A. Melnikov, Yu. G. Selivanov, S. V. Chekalin

Selective excitation of coherent high-amplitude vibrations of atoms in a solid can induce exotic nonequilibrium states, in which the character of interactions between electronic, m…

Effect of Sr doping on structure, morphology and transport properties of BiSe epitaxial thin films

S. O. Volosheniuk, Yu. G. Selivanov, M. A. Bryzgalov +2

We report molecular beam epitaxy growth of Sr-doped BiSe films on (111) BaF substrate, aimed to realize unusual superconducting properties inherent to SrBiSe$_3…
