Broadband dielectric spectroscopy (BDS) was used to study thin films of Ge2Sb2Se5 exposed to low fluence UV-irradiation that resulted in thermally reversible
Historically, the evaluating solder joint failures and solder joint reliability have been done with DC methods using event detectors or data loggers for high
