Compared to NCTU, which is very technology-oriented, NTHU's R&D strength lies mainly in basic R&D. Physics, Chemistry, and Materials Science have been the strongest fields of study at NTHU. Nanoparticle/ nanostructure R&D, however, is in its initial stage and is carried out mostly at the Materials Science Center.
There are several groups actively working on projects related to nanoparticle technology.
Professor David Z.Y. Ting, a condensed matter theorist, has developed techniques to study (1) disorder effects in semiconductor alloys and superlattices; (2) electronic and optical properties of quantum wells and superlattices; (3) heterostructure tunnel device physics; (4) 3-D modeling of quantum transport in nanostructures; and (5) light extraction from light-emitting diodes. His current research projects include
Professor S. Gwo of the Physics Department has been involved in the growth of self-organized semiconductor nanostructures by MBE. He has ample experience in nanostructure fabrication for advanced electronic and optoelectronic devices. He is also involved in the atomic-scale studies of dopants in semiconductors and in the development of UHV scanning probe microscopy and spectroscopy for optical measurements. Professor T.P. Peng of the Department of Materials Science and Engineering (in collaboration with Professor M.K. Wu and Dr. S.R. Sheen of the Materials Science Center), has been working on the preparation of nanoparticles by vapor condensation, high-energy ball milling, or magnetron sputtering. Their current research projects cover
Impressive progress has been made in nanoparticle/nanostructured research at NTHU. Under the leadership of Professors M.K. Wu and C.C. Chi, the university has established a network connecting the microfabrication capabilities of NCTU, the chemical processing techniques of NTU, and the analytical and materials processing capabilities at their own Materials Research Center to perform the only organized research effort in this area. They also plan to expand their characterization capabilities to include some of the atomic force microscopy techniques developed at the Academia Sinica. Their future research activities will be directed toward semiconducting functioning materials and nanophase materials for biological sensor applications.
