Dr. Tar-pin Chen’s research involves nanometer devices and materials. His group is working on characterizing and making insulator for high transition temperature superconductor-insulator-superconductor Josephson junction (SIS junction). The thickness of the SIS junction should be thinner than 4 nanometers, yet provide sufficient potential barrier for the junction. In recent years, his group had discovered new insulator materials, which even as thin as 1.2 nanometer, is capable of providing high enough potential barrier for making SIS junctions with high enough critical current for making nanometer devices.
Using this insulator material Dr. Chen’s group is working on making SIS Josephson Junction which will be used to make SQUID, the most sensitive devices for measuring magnetic flux and magnetic cardiology graph, a device more sensitive than EKG and can dictate heart disease at an earlier sate than EKG. It can also be used to make terahertz dictators to detect terahertz signals. It can also be used to make the key elements for quantum computers.
Other research interest of Dr. Chen’s group is to make nanometer thickness organic solar cell materials, quantum bit devices and terahertz dictators.
In 2005 UALR is awarded $6,000,000 to establish a nanotechnology research center. Physics is one of the most important fields in nanotechnology. The physics and astronomy department of UALR recruit a chairperson to lead in nanotechnology research. For this reason I accept the challenge and came to UALR.
Nanotechnology is still a pretty new research field in science. New discovers has been coming from physics, biology, and chemistry research. Industries begin to make use of the technology and fabricate useful products. I am expecting new discovers in nanotechnology will continue and knowledge in understanding the properties of nano-materials will improve and industrial products using the techniques will increase. Our project in study nano-solar cell material will have a good progress in the next five years.
