Photoelectret Properties of (HgO-Fe2O3) Mixed Material

Dr. Meenu Singh Sachan

Abstract: In this paper the photoelectrect properties of (HgO-Fe2O3) mixed material have been studied. The Fe2O3 is poor photoelectret but when HgO is mixed with Fe2O3 then it shows photoelectret characteristics. The HgO which forms mixed material with Fe2O3 in different compositions, shows maximum photoelectret charge (Qph) for (75 % HgO- 25 % Fe2O3), sample. For all the three composition i. e. (75 % HgO-25 % Fe2O3), (50 % HgO - Fe2O3) and (25 % HgO - 75 % Fe2O3) the photoelectret charge has been found to be greater than the base material 100 % HgO and 100 % Fe2O3. The dependence of photoelectret charge on various parameters such as applied field, intensity of illumination, charging time and dark depolarisation time has been studied to get the optimum condition of maximum charge storage.
