RT Journal Article T1 Scanning tunneling spectroscopy of transition-metal-doped GaSb A1 Hidalgo Alcalde, Pedro A1 Méndez Martín, María Bianchi A1 Piqueras De Noriega, Francisco Javier A1 Dutta, P: S. A1 Dieguez, E. AB V- and Ru-doped GaSb crystals have been investigated by scanning tunneling spectroscopy in a combined scanning electron microscope-scanning tunneling microscope system. Local variations of surface band gap have been measured with high spatial resolution. Precipitates in both kinds of doped samples show a nearly metallic behavior. The surface band gaps in the GaSb matrix have been found to depend on the dopant. [S0163-1829(99)06439-5].
