Research interests:

Physics of Semiconductors; Physics of Narrow-Gap Semiconductors; Terahertz Radiation Detectors; Organic Semiconductors, Physics of Semiconductor Nanostructures.

Main Results:

A range of new effects has been observed on heavily doped lead telluride-based narrow-gap semiconductors. These effects include:
  • Giant negative magnetoresistance with the amplitude exceeding 106.
  • Localization and delocalization in ultrahigh magnetic fields, mircrowave stimulation persistent photoconductivity that allows increasing the quantum efficiency of a semiconductor up to 102.
  • Microwave resonance of the persistent photoconductivity, selective phonon- stimulated photoconductivity observed at terahertz frequencies, and many others.
  • Physical principles of operation of a new type of sensitive photodetecting devices working in terahertz and infrared ranges have been developed. A laboratory model of terahertz radiometer has been constructed. Some parameters of this radiometer including responsivity, spectral range of photoresponse, radiation hardness, and others, exceed all state of the art analogs.
  • A possibility for realization of a high-performance “continuous” focal plane array operating in the terahertz spectral range has been suggested and experimentally founded.

Beside the areas mentioned above, a range of new directions of research is developed including investigation of electrical transport, photoelectric and optical phenomena in supramolecular organic semiconductors, group III nitrides, and some other materials.
