Chioncel, M. F. ; Díaz-Guerra Viejo, Carlos ; Piqueras de Noriega, Javier ; Vincent, J. ; Bermudez, V. ; Dieguez, E. | Elsevier Science B.V. | 2004-07-15The nature and the spatial distribution of radiative defects in InxGa1-xSb grown by the vertical Bridgman method have been studied by cathodoluminescence (CL) in a scanning electron microscope. The CL results have been complemented by X-ray micr[...]texto impreso
Díaz-Guerra Viejo, Carlos ; Vincent, J. ; Piqueras de Noriega, Javier ; Bermudez, V. ; Dieguez, E. | American Institute of Physics | 2005-01-15The radiative recombination properties of Se-doped GaSb crystals grown by the Bridgman method have been investigated by cathodoluminescence (CL) microscopy and spectroscopy in the scanning electron microscope. A CL band centered at about 765 meV[...]texto impreso
Vincent, J. ; Díaz-Guerra Viejo, Carlos ; Piqueras de Noriega, Javier ; Amariei, A. ; Polychronladis, E.K. ; Dieguez, E. | Elsevier Science B.V. | 2006-03-15Undoped and Te-doped GaSb ingots have been grown by the vertical feeding method. The structural, optical and electrical properties of the grown crystals were respectively investigated by X-ray diffraction, transmission electron microscopy, catho[...]
