Abstract
Analysis of Auger parameter shifts in amorphous CuHf alloys of varying composition give insight into charge transfer and core hole screening, which is useful in understanding the anomalous electronic properties of these materials. The copper Auger parameter, which can be determined very precisely, increases upon addition of hafnium, but shifts in the hafnium Auger parameter are difficult to isolate due to peak overlap. However, Hf4f and Cu2p shift in opposite direction with composition variation, which, in conjunction with the Auger parameter data, suggests electron transfer from hafnium to copper.
