Lab Overview
1. Advanced Materials Processing Laboratory has been performing the various co-operative educational projects
in the electric & electronic material fields such as semi-conductive sensors and solid state ionic conductors, etc.
since 1999. Recently, our group has been intensively focused on synthesis of nanostructures, fabrication of
nanoceramics, development of new phosphor materials, and formation of anti-corrosive films.
