Özet:

 

The present paper reports dc conductivity measurements at  high electric fields in vacuum evaporated a-Se1 - xSbx (x = 0,  0.02, 0.04, 0.06) thin films.  At high fields (~ 104 V .cm-1), current can be modelled by the theory of space  charge-limited conduction in the case of uniform distribution of  localised states in the mobility gap of these materials.  The addition  of Sb in Se results in an increase in the density of localised states.
