Quantum-size effects in semiconductor heterosystems
Journal Title: Semiconductor Physics, Quantum Electronics and Optoelectronics - Year 2017, Vol 20, Issue 2
Abstract
Created on the basis of Si, GaAs and C60 fullerenes were low-dimensional heterostructures with a surface quantum-size effect at the film-substrate interface. There have been defined technological conditions of its appearance. Using modulation electroreflectance spectroscopy, calculated were spectral broadening parameters, the energy relaxation time of excited light charge carriers, the energy of quantized levels and the width of the quantum wells.

The influence of ethylene glycol on the chemical interaction of PbTe and Pb1–xSnxTe crystals with H2O2–HBr–ethylene glycol etching compositions
The process of cutting, mechanical and chemical treatment of the PbTe and Pb1–xSnxTe crystal surface has been studied. The dependences of the chemical-mechanical polishing rate versus dilution of the base polishing etcha...
Oxygen ion-beam modification of vanadium oxide films for reaching a high value of the resistance temperature coefficient
A new method to prepare vanadium oxide with a high temperature coefficient of resistance (TCR) and low resistance for uncooled micro-bolometers has been proposed. Amorphous vanadium oxide films with V2O3 phase inclusions...
Dose dependence of tensoresistance for the symmetrical orientation of the deformation axis relatively to all isoenergetic ellipsoids in γ-irradiated (60Co) n-Si crystals
The dose dependence of tensoresistance X /0, which was measured at the symmetrical orientation of the deformation axis (compression) relatively to all isoenergetic ellipsoids both in the initial and in -irradiated sam...
Nanocrystalline silicon carbide films for solar cells
Nanocrystalline silicon carbide (nc-SiC) films as protective coating and as solar cell material for a harsh environment, high temperatures, light intensities and radiation, were investigated. p- and n-types 100-mm silico...
Fluorescence of molecules placed near a spherical particle: Rabi splitting
Theoretical study of spontaneously emitted spectra of point-like source placed near spherical Ag particle was performed. It was shown that near-field electromagnetic interaction between a point-like emitter and spherical...
