RT Journal Article T1 Decoration of extended defects in GaSb by Al doping as evidenced by cathodoluminescence studies A1 Hidalgo Alcalde, Pedro A1 Méndez Martín, María Bianchi A1 Piqueras De Noriega, Francisco Javier A1 Dutta, P.S. A1 Diéguez, E. AB The effect of aluminium on the defect structure of GaSb crystals, grown by the vertical Bridgman technique, has been investigated by cathodoluminescence (CL) in the scanning electron microscope. Crystals have been found to be highly homogeneous along the growth axis with the exception of the top end which showed Al accumulation. The CL results show decoration of extended defects by Al but contrary to the case of other dopants Al has not been found to cause a significative reduction of native accepters. A CL band at about 850 meV appears to be related to the presence of aluminium.
