Theoretical and experimental study of nanostructured functional materials perspective for gas sensors and optoelectronics

Theoretical and experimental study of nanostructured functional materials perspective for gas sensors and optoelectronics

The work aims to create, experimental and theoretical study of nanostructured functional materials based on Si, Ge, C and ZnO in order to determine their fundamental properties for further use of these materials in optical and sensor electronics, in particular as electrically active elements, thin functional layers, light-emitting materials in optoelectronic devices, means of visualization, light indication and gas sensors and subwavelength optical micromechanical devices.

Theoretical and experimental investigations of electronic, magnetic and optical properties of nanosized carbon-containing materials

Luminophores of “white light” are an important part of white-light-emitting diodes, and the main part of these diodes consists from UV light sources (usually an InGaN based light-emitting structure) and a luminophor transforming UV into a broad spectrum of white light. To date, rare earth or heavy metals are the main components of luminophors leading to its recycling complexity and increase in manufacturing costs. Moreover, the spectral characteristics of the modern commercial luminophors do not correspond to the spectral characteristics of the sunlight.
