Thermally stimulated exoelectron emission from solid Xe
Thermally-stimulated emission of exoelectrons and photons from solid Xe pre-irradiated by low-energy electrons were studied. A high sensitivity of thermally-stimulated luminescence (TSL) and thermally-stimulated exoelectron emission (TSEE) to sample prehistory was demonstrated. It was shown that e...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | Thermally-stimulated emission of exoelectrons and photons from solid Xe pre-irradiated by low-energy
electrons were studied. A high sensitivity of thermally-stimulated luminescence (TSL) and thermally-stimulated
exoelectron emission (TSEE) to sample prehistory was demonstrated. It was shown that electron traps
in unannealed samples are characterized by a much broader distribution of trap levels in comparison with annealed
samples and their concentration exceeds in number that in annealed samples. Both phenomena, TSL
and TSEE, were found to be triggered by release of electrons from the same kind of traps. The data obtained
suggest a competition between two relaxation channels: charge recombination and electron transport terminated
by TSL and TSEE. It was found that TSEE predominates at low temperatures while at higher temperatures
TSL prevails. An additional relaxation channel, a photon-stimulated exoelectron emission from pre-irradiated
solid Xe, was revealed. |
