Role of the Critical Voltage Effect in Materials Characterization

Abstract

ABSTRACTThe HVEM “critical voltage” effect can provide quantitative information about intrinsic crystal parameters that cannot be obtained easily on a microscopic scale by other techniques. For pure elements, more accurate atomic scattering amplitudes and Debye temperatures have been determined. In binary alloys, the occurrence of segregation, short or long range order or clustering can be evaluated and charge distribution or transfer and atomic bonding changes detected in favorable cases.
