Metal oxide thin films with highly ordered nanostructures for high performance gas sensors

Ho Won Jang

Seoul National University

Nanostructured oxide thin films can greatly improve the efficiency and performance of many devices including solar cells, secondary batteries, fuel cells, gas sensors, light emitting devices, and photoelectrochemical water splitting systems. However, synthesis-and-place methods which are commonly used to fabricate nanostructured oxide thin films often lack reproducibility, durability, and reliability. In the talk, we will present our approaches to synthesize highly ordered nanostructured oxide thin films on the desired locations using various synthesis-in-place methods such as colloidal templating, glancing angle deposition, anodization, and hydrothermal method [1-3]. We will show the demonstration of high performance gas sensors using the synthesized thin film nanostructures.
