摘要: ZnO/In/ZnO tri-layer thin films were designed and fabricated by RF sputtering on copolymer substrate. Under an electrical current, the thermoelectric effect of direct current (DC) reduced resistance improved crystallization Raman properties. Also, indium atoms had migrated into ZnO matrix a diffusion layer in ZnO/In interface grown. The induced temperature is ∼140°C substrate suffers no damage so can be applied to low optoelectronic devices.
