DX-like centre in bulk GaSb:S

Hall, conductance, capacitance transients and DLTS measurements were carried out on Czochralski grown GaSb doped with sulphur. A deep centre with a small and temperature dependent capture cross section and with a high concentration was observed. Such features together with the detected persistent ph...

Zusammenfassung:	Hall, conductance, capacitance transients and DLTS measurements were carried out on Czochralski grown GaSb doped with sulphur. A deep centre with a small and temperature dependent capture cross section and with a high concentration was observed. Such features together with the detected persistent photoconductivity indicate that the observed centre is sulphur related DX-like centre. Some properties of the centre are presented and discussed.
