The results of the investigations of thermally stimulated electron emi
ssion from graphite submitted to intercalation of K-Bi alloy, in the t
emperature range of 100-400 K, are presented. Total and partial pressu
re in the measuring chamber in relation to the temperature of the samp
le are also reported. The insertion of a K-Bi alloy into the interlaye
rs of graphite considerably changes thermally stimulated electron emis
sion properties. The emission images I(T) depend on the content of int
ercalate 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 desorpt
ion of gases at a temperature over 250 K does not cause any increase i
n the electron emission.
