Abstract
The energy distribution of gap states in methylbixin crystallites has been investigated by photoconductivity decay measurements. The results show that the shallow states decrease exponentially with characteristic temperature T c∼900 K at an applied field of 1.77×103 V/cm. T c is independent of sample temperature but depends inversely on applied field. It is suggested that field effect on T c may arise from the field effect on trapping rate.Keywords
