“…This case is attributed to the nonideal behavior (current transportation) of poly(AAm-co-HEMA)-ZnO based Si heterojunction diodes, considering the inhomogeneous barrier distribution, series resistance, interface film layer, tunneling effect and interface states, recombination and minority carrier injection [22][23][24]. The ideality factor was found to be 2.36 for the diode based on ZnO thin films synthesized by thermal decomposition method and formed on p-Si [25]. The transport mechanism is considered based on electron-hole recombination at low values of n (n~2) [26].…”

poly(AAm-co-HEMA)-ZnO is synthesised by hydrothermal method. poly(AAm-co-HEMA)-ZnO nanocomposite is coated by the drop casting technique on p-Si substrate. The current-voltage (I–V) measurements of Al/poly(AAm-co-HEMA)-ZnO/p-Si heterojunction diodes with (a) 1%, (b) 3% and (c) 5% ZnO are carried out in the dark and illumination intensities of 20–100 mW/cm2 with 20 mW/cm2 steps. It is seen that the optimized or high rectification ratio is possible to obtain in metal/p-Si contacts by suitably choosing ZnO rate in poly(AAm-co-HEMA)-ZnO nanocomposite. The I-V characteristics show exactly the characteristic feature of a photodiode. It is seen that the detectivity (D) and photosensitivity (PS) are more efficient than that of the structure formed without any of the components of nanocomposite. The interface state density (Dit) varies depending on the amount of ZnO in poly(AAm-co-HEMA). Results show that poly(AAm-co-HEMA)-ZnO can be employed in the design of optoelectronic devices, as well as biomedical applications as biomaterial.
