Preliminary investigations of the thermostimulated electron emission (
TSEE) from intercalate type K1.1BiC7.36, in the 300-600 K temperature
range, were performed. The total and partial pressure in the apparatus
during heating and cooling of the sample were also recorded. A maximu
m in the electron emission at a temperature of about 320 K, and a dras
tic rise in the electron emission, which was accompanied by a rise in
the total ambient pressure at 570 K, were observed. The increase of pa
rtial pressures of H2O, CO (N2), and CO2 contribute to the total press
ure as measured at 570 K by means of the unipole mass spectrometer (UF
M). The activation energy, using the method of numerical curve fitting
, was calculated to be E = 0.72 eV for the 320 K peak.
