DLTS spectra of the resistively deposited (control) Pd Schottky contacts to reveal that these samples contain no electron or hole traps [curves and , respectively] within the detection limit of our DLTS system. Curves and are the DLTS electron and hole trap spectra, respectively, of Pd Schottky contacts deposited by EBD, recorded using a rate window of at a quiescent reverse bias of . For the electron-trap spectra the pulse was into forward bias. Hole trap spectra were obtained by applying an injection pulse of into forward bias. Curves and are the spectra for electron irradiated resistively deposited Pd Schottky contacts to , recorded under the same conditions as curves and , respectively.
