We report on fabrication of two-dimensional metallo-semiconductor networks by using pulsed electroplating Pt inside electrochemically-prepared porous GaP layers with parallel pores possessing diameters in the micrometer and sub-micrometer ranges. The electrochemical parameters were optimized for a uniform metal deposition inner surface template. A variable capacitance device fabricated Pt/GaP Schottky diodes forming at interface interpenetrating showed much higher density variation as...
Absorption (K), reflection (R) and wavelength modulated transmission (ΔT/Δλ) spectra in SnS2 crystals of hexagonal phase (space group P63/mmc) were investigated temperature interval from 300 to 10 K. It was established that indirect band gap ( - 2.403 eV) is due unpolarized transitions between Γ M points Brillouin zone. A minimal direct 2.623 E∣∣b polarization formed by allowed E⊥b (2.698 forbidden point magnitude refractive index (n) changes 3 4 has a maximum at 2.6 eV. Optical functions...

Luminescence, transmission, reflection, and wavelength modulation transmission reflection spectra of HgGaInS4 crystals were researched in the temperature range 300-10 K. This article discusses various features observed crystals. The dependence on energy gap is shown. Spectra have minima a1, a2, a3, which vary with are caused by indirect transitions L-Г phonon absorption emission. thicker more same transitions. photoluminescence show a strong maximum at 2.43 eV, attributed to radiative...
