Knowledge sharing seminar

Assoc. Prof. Tho Nguyen

Department of Physics and Astronomy, University of Georgia, USA


Assoc. Prof. Tho Nguyen

We are very happy to welcome Assoc. Prof. Tho Nguyen to a knowledge sharing seminar of the GSC Network in March 2022. In a friendly and open-minded environment, we will discuss about research and collaborative potentiality. You are most welcome.


Dr. Tho Nguyen received a dual degree in Physics and Computer Science in 1996 and 1998, respectively, at Can Tho University. He spent 5 years as a physics teacher at Chau Van Liem high school, Can Tho. He got a scholarship from the Ford Foundation in 2001 to pursuit his MS degree in Science Education at the University of Iowa. He got the MS degree in 2004, and then his PhD in Condensed Matter Physics from the same university in 2008. After that he went for a postdoctoral stay at the University of Utah until 2010. He was promoted to Research Assistant Professor in the same institution. He started his Tenure Track Assistant Professor at the University of Georgia in 2012 and was promoted to Tenure Associate Professor in 2019. He has published above 70 peer-reviewed papers and has achieved two US patents.


Spintronics in Organic Semiconductors and Perovskites, Magnetoplasmonics and their Applications


Spin sense of electrons has attracted considerable research and technological attention for over past several decades. The spin of the electrons in atoms is the main source of ferromagnetism and the main subject to spin electronics (spinstronics). In this talk, I will have a brief introduction to my research both on fundamental studies and applications of spintronics and magnetoplasmonics. First, I will discuss spintronics in organic semiconductors, and organic-inorganic hybrid perovskites. Organic semiconductors possess weak hyperfine interaction and spin-orbit coupling, and hence long spin lifetime, suitable for quantum materials for spin manipulation, but they have very poor charge mobility. In contrast, perovskites have a strong spin-orbit coupling (both intrinsic and extrinsic ones like Rashba-Dresselhaus) causing relatively small spin lifetime, but the charge diffusion length is extremely long. Some spintronic devices made by those materials (spin valves, spin LED, …) will be discussed. Next, I will talk about magnetoplasmonic effects where the light-magnet interaction is greatly enhanced resonantly at the localized surface plasmon modes. Finally, I will show some current and future applications (gas sensing, semitransparent solar cells…) of above studied materials and phenomena.
