The nanocomposited ZnO/SnO2 thin film were synthesized by thermal chemical vapour deposition (CVD) on ZnO coated glass as template layer. Based on the FESEM observations, different composite nanostructures grew on the ZnO template layer for different Sn precursors; Tin TetraChloride, Dibutyltin Diacetate and Tin Powder. The photoluminescent of nanocomposited ZnO/SnO2 thin film indicated low peak at...
Innovative advance dielectric materials were utilized to fabricate novel thin film capacitor device.

Metal acts as a passive layer on semiconducter in order to stabilize the surface against chemical and heat-induced changes. The passive layer controls surface recombination, leakage, and related noise as well.
