Scanning electron acoustic microscopy of indium-doped semi-insulating GaAs

Dislocation lines in {110} sections of In-doped GaAs are imaged by scanning electron acoustic microscopy (SEAM). Cathodoluminescence measurements show the presence of a high indium concentration at dislocations. It is proposed that the semi-insulating property of the sample and dislocation decoratio...

Sumario:Dislocation lines in {110} sections of In-doped GaAs are imaged by scanning electron acoustic microscopy (SEAM). Cathodoluminescence measurements show the presence of a high indium concentration at dislocations. It is proposed that the semi-insulating property of the sample and dislocation decoration contribute to the SEAM contrast.
