"electron-phonon interactions not only account for the entirety of the hhe process, which was hypothesized in previous works but never conclusively demonstrated, but also for a significant portion of the eeh process, a finding that had been a subject of unresolved debate in the literature... important intrinsic loss mechanism in silicon, world's most important semiconductor...  reducing occurrence of undesirable Auger-Meitner recombination process... transistors or solar cells"
