Physics Colloquium - Dr. Yoke Khin Yap of MTU, Department of Physics

Dr. Yoke Khin Yap will present "Functional Boron Nitride Nanostructures for Advanced Electronics and Biomedicine" on Thursday, March 7th at 4:00 pm in Fisher Hall, Room 139.

Abstract: This seminar will discuss about functionalization of boron nitride nanotubes (BNNTs) and boron nitride nanosheets (BNNSs) for advanced electronics and biomedicine.
The miniaturization of silicon field effect transistors (FETs) is limited by semiconductor physics such as short channel effects and high resistive heating. Tunneling field effect transistors (T-FETs) were developed to partially resolve these issues. Our work on T-FETs without using semiconductor will be discussed in the seminar. In addition, the use of electrically insulating and thermally conducting BNNTs and BNNSs in promoting heat dissipation will be discussed.
Next, high-brightness dyes based on functionalized BNNTs will be discussed for their usage in flow cytometry. Multicolor flow cytometry can sort and count thousands of cells per second. This is a laser fluorescence technique indispensable for clinical screening of blood diseases, as well as immunology, cancer, and stem cell research. The performance of this technique is limited by “auto-fluorescence” and “spill-over”. Our high-brightness dyes are a few thousand times brighter than commercial products. This allow us to overcome the above mentioned issues to identify rare biomarkers on cells.

Bio: Dr. Yoke Khin Yap is a professor of physics, and the director of applied physics graduate program at Michigan Technological University (MTU). He earned his Ph.D. in 1999 from Osaka University as supported by the “Monbusho” scholarship. He was a postdoctoral fellow of the Japan Society for the Promotion of Science (JSPS) before his appointment at MTU. Professor Yap was honored with the U.S. National Science Foundation CAREER Award (2005), MTU Bhakta Rath Research Award (2011), Osaka University Global Alumni Fellow (2015), and MTU Research award (2018). His current research interest is low dimensional materials for advanced electronics, biomedicine, energy production, and water purification.
