Dislocation Filter Based on LT-GaAs Layers for Monolithic GaAs/Si Integration
The use of low-temperature (LT) GaAs layers as dislocation filters in GaAs/Si heterostructures (HSs) was investigated in this study. The effects of intermediate LT-GaAs layers and of the post-growth and cyclic in situ annealing on the structural ...

First vertical-cavity surface-emitting laser made entirely in Poland [PDF]
The paper presents the first vertical-cavity surface-emitting lasers (VCSELs) designed, grown, processed and evaluated entirely in Poland. The lasers emit at »850 nm, which is the most commonly used wavelength for short-reach (

Application of Scanning Hall Probe Microscopy Technique at Room Temperature 300K. [PDF]
Active areas of bismuth Hall Probe sensors in the range (0.1 – 1) µm have been fabricated on Si/SiO2 with GaAs substrates at thickness of bismuth from (40, 60 and 70) nm by Electron Beam Lithography (EBL) and lift-off process.

Characterization of Gaas/Si/GaAs Heterointerfaces [PDF]
ABSTRACTTransmission electron microscopy of GaAs grown on Si for metal-semiconductor-metal photodetectors is presented in this paper. Two kinds of samples are compared: GaAs grown on a 15 Å Si epilayer grown on GaAs, and GaAs grown at low temperature (300°C) on Si substrates.

Specific Design Features of Charge Sensitive Amplifiers on Arsenide-Gallium Master Slice
For the production of integrated analog circuits with a small-scale integration, which are developed to operate at temperatures up to minus 200 ℃ and/or with absorbed dose of gamma radiation up to 5 Mrad, a gallium arsenide master slice has been created.
