Abstracts

EN

The results of the investigations of thermally stimulated electron emission from graphite submitted to intercalation of K-Bi alloy, in the temperature range of 100-400 K, are presented. Total and partial pressure in the measuring chamber in relation to the temperature of the sample are also reported. The insertion of a K-Bi alloy into the interlayers of graphite considerably changes thermally stimulated electron emission properties. The emission images I(T) depend on the content of intercalate and the emission maxima obtained at temperatures of about 170 and 210 K are conditioned by the desorption of a gas while the total pressure above the different samples is of the same order. The desorption of gases at a temperature over 250 K does not cause any increase in the electron emission.
