Photoconductivity studies of (PbCrO4-HgO-ZnO) composites

ZnO nanoparticles: Structural, optical and photoconductivity characteristics

“…The non-Ohmic super-linear variation of darkcurrent (2 > r > 1) suggests that some carriers are being injected into the materials form one of the electrodes [33,34,53,54]. At higher voltages, the darkcurrent varies with voltage according to a power greater than two (r > 2) for both the samples.…”

“…Super linear behavior of the photocurrent suggests that some carriers are being injected into the material from one of the electrodes [33,34,53,54]. The values of 'r' for darkcurrent as well as photocurrent are listed in Table 1.…”

“…The p-values corresponding to different exponentials have been calculated by the relation [13,[33][34][53][54][60][61][62]:…”

“…Extensive study of photoconducting properties has been made in nanoparticles, thin films, nanorods, nanowires and mixed lattice [12][13][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34] for different parameters.…”

Investigation of photoconductivity in Pr-doped ZnS powder prepared by simple heat treatment technique

“…It is well known that the rise and decay curves of photocurrent are governed by the trapping states or recombination centers lying in the forbidden energy zone of a photoconductor. Therefore these curves can be used to understand the nature and distribution of traps and recombination centers [3][4]. Photoconductivity in powder has been investigated by many workers [5][6][7][8][9][10].…”
