The effect of Ar+ (400 keV) and Xe++ (700 keV) bombardment and consecutive annealing (250–525 °C for 10 min in forming gas) on the electrical behaviour of n-type Au/GaAs Schottky junctions are studied. The obtained anomalous I–V and C-V characte

Surface properties and morphology of the mirror-like GaAs and GaSb substrate wafers for MBE and VPE growth were studied using whole sample optical reflection (“magic mirror”, or “Makyoh” phenomenon). Samples with various surface treatments we

Thinning of epitaxial GaAs layers was studied during the surface etching, with a special attention to submicron epitaxial structures, like MESFET or varactor-type structures. Each chemical treatment influences the crystal surface during the device pr

The AuGe/Ni/Au metallization is one of the most widely used contact structures in compound semiconductor devices. Many laboratories use a metal structure consisting of a AuGe eutectic (88 : 12) layer with, typically, 5% Ni. The influence of Ni propor

Recently discrepancies were obtained between the barrier heights evaluated from the I-V and C-V measurements of Au/CrGaAs Schottky contacts and between the experimental and theoretical concentration dependences of the built-in potential obtained f

The composition, refractive index and thickness of thermally grown SiO2 layers grown onto Si single crystals were investigated by attenuated total reflection spectroscopy (ATR) and ellipsometry. Under laboratory storage conditions the value of the re

It was shown earlier that there is a peak at about 260 K in the thermostimulated current spectrum of metal/oxide/semiconductor structures treated by a standard procedure. In this paper we report further results obtained by analysing the origin of thi
