ONG Chong Kim

Professor of Physics

• Prof Ong ‘s research interests are in the science of Superconductivity, Ferroelectricity and Magnetism. His research group fabricates high quality multilayer thin films and quasi one dimensional nanostructure, and designs and realizes “proof of concept” prototype devices and systems exploiting the advantages offered by multilayer thin films. His current projects include: (i)Miniature and Tunable Devices for Wireless Applications, (ii) Microwave properties of quasi-one-dimensional nanostructures, (iii) Study of multiferroic magnetic oxides, (iv) Transparent Conducting Oxides and Oxide p-n junctions for novel electronics, (v) Transport Properties of Oxide Nanocontact, (vi) Study of Magnetic Thin Films for Development of Microwave Absorbers, (vii) High temperature superconducting SQUID for immunoassays.
