Development of low temperature laser annealing system suitable for realization of functional metal oxide nanostructures
In collaboration with Dr. Seung-Nam Cha and Dr. Jong-Min Kim, both at SAIT, we are investigating the crystallization of sol-gel based metal oxide systems both in a thin film and in a patterned nanostructure using a low temperature laser annealing system. With conventional method, high temperature and long heat treatment time are normally required, thus limiting the use of certain substrates such as glass or ITO substrates and the efficient use of energy. Using our laser annealing system, on the other hand, we can easily realize functional metal oxides at relatively low temperature (3000C) over extremely short heat treatment time (in less than a few minutes). We are to investigate the effects of different atmosphere during the heat treatment on the functionalization of metal oxides on different substrates.
