Electrical activity of misfit dislocations in GaAs-based heterostructures
Electrical properties of lattice-mismatch induced defects in GaAs/InGaAs and GaAs/GaAsSb heterostructures have been studied by means of electron-beam induced current (EBIC) in a scanning electron microscope and deep-level transient spectroscopy (DLTS). DLTS measurements, carried out with p-n junctio...
