Fabrication and Characterization of ZnO/p-Si and TiO sub(2)/p-Si Heterojunctions for Hydrogen Detection-Influence of Pd Functionalization

Nanocrystallyne n-ZnO and p-TiO sub(2) thin films were deposited on crystalline Si substrate by the simple and low-cost sol-gel method. The surfaces of nanocrystalline ZnO and TiO sub(2) were modified by PdCl sub(2) solution to passivate the defect states and to improve the gas sensitivity. Both unm...
