Energy distribution of thermostimulated electrons, emitted from KClAg

Retarding field dependences of thermostimulated electron emission (TSEE) from KCl-In and KCl-Ag

“…The broad dj'/dU curves for TSEE a r e ip accordance with the results obtained C by "normal" energy distribution measurements for thermostimulated electrons emitted from KC1-Ag in (1) and from a number of various other substances (references in (1)). If they reflect the real energy distributions, rather high maximal (2 to 2.1 eV)…”

“…

Energy distributions of thermostimulated electrons from various substances (e.g. (1) and references therein) have been determined only in planar geometry devices with the aid of Geiger-Muller counters o r electron multipliers. Thus, the full energy distributions cannot be extracted from the experimental data, and a distortion of the distributions by detector fields is possible.

Itis unusual for ordinary thermionics and shows that the conception of simple equilibrium thermionic emission from the conduction band i s not adequate to explain the TSEE process.…”
