Overview

Our team focuses on different solution processed thin film deposition for various applications like electronics/optoelectronics, energy and health. We primarily concentrate on sol-gel derived ion-conducting metal oxide, metal oxide semiconductors and various nanostructured materials for thin film deposition. Ion-conducting oxide thin film has mobile light atoms like Li+, Na+, K+ which can move easily through the solid thin film. This kind of ionic thin film has very high areal capacitance which can be suitable for fabricating low operating voltage thin film transistors (TFTs). Besides, light atoms of ionic oxide can be exchanged easily with other ions like Ag+, Au+, Cu+, which allow us to grow different metal and metal chalcogenide nanocrystal inside oxide materials. These metal /metal oxide or metal chalcogenide /metal oxide thin film has various applications for optoelectronics devices and energy generation. Besides, we grow different nanocrystal by microwave assisted synthesis, hot-injection and hydrothermal process for thin film device application.
