The results of a study of the temperature dependence of current transp
ort in Pd/LB-film/n-Si diodes are presented. The current-voltage (I-V)
characteristics are found to display strong temperature dependence fo
r reverse and low forward bias. Such behaviour is not expected for a m
ajority carrier Schottky diode. It is suggested that these structures
are minority carrier tunnel diodes in which semiconductor related curr
ent transport plays an important role in determining the device I-V ch
aracteristics. At, high forward bias the current is tunnel limited. (C
