Deterministic Periodical and Quasiperiodical Surfaces of III-V Compounds: Preparation, Investigations and Applications

Autocorrelation functions for rough (random, quasiperiodical and deterministicperiodical) surfaces are deduced from the surface profiles determined by using the line-by-line analysis of atomic force microscopy images. It is shown that the initial parts of autocorrelation functions have a Gaussian form. An attempt to use the concept of fractal as a bridge between deterministic periodic and random (spontaneous) surfaces including quasiperiodic ones have been made

Contribution of Structure and Morphology of Design Constituents to Performance Improvement of Multilayer Polaritonic Photodetector

This paper is devoted to estimate contribution of structure and morphology of the individual design constituents to performance improvement of multilayer polaritonic photodetector (optochemical sensor). Surface plasmon resonance (SPR) in the surface barrier heterostructure (SBH) with the corrugated interface is used as the basic principle underlying the device operation. The demonstration of correlation of the contribution with the enhanced SBH features was performed through the adequate characterization tool
