Temperature dependence of photoelectron angular distribution from thin films of chloroaluminum phthalocyanine on MoS(2).
Angle-resolved UV photoelectron spectra were measured for thin films of chloroaluminum phthalocyanine deposited on cleaved MoS(2) surfaces. The take-off angle (theta) dependence of the photoelectron intensity of the highest pi band showed a remarkable sharpening upon cooling the film, indicating that thermal excitation of molecular vibrations gives a considerable broadening of the photoelectron angular distribution. The theta dependence observed at approximately 120 K agrees well with that calculated.
