Abstract
GaSb and GaInSb compounds were synthesised from the component elements using a new technique. The effect of the electro-magnetic induction on the conductor materials is used in order to heat, melt and mix the Ga, Sb and In elements. The homogeneity and the structural quality of the elaborated feed materials were verified by using different techniques: Scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), Rutherford backscattering (RBS), Particle-induced X-ray emission (PIXE), Cathodoluminescence in the scanning electron microscope (SEM-CL), Wavelength dispersive X-ray microanalysis (WDX), Transmission electron microscopy (TEM). It is found that the GaSb material totally reacts but GaInSb alloys present heterogeneities at the micro-and macroscale.
