SPS Alumni Talk

 

The Special Programme in Science (SPS) held its second alumni talk on 1 March.

 

Dr SIU Zhuo Bin, from SPS 2004, shared on his research interests in the field of nanoelectronics and nanospintronics, where he is currently investigating the use of topological insulators and other emerging materials for practical device applications. In his talk, he gave an introduction to topological insulators from the perspective of a computational physicist working in NUS’ Faculty of Engineering. He also discussed how topological insulators bring together abstract mathematics, condensed matter physics and engineering to form a field of interdisciplinary research at the interface between science and engineering.

 

Topological insulators are an emerging class of materials which have drawn widespread interest due to their fascinating properties from the perspective of fundamental physics as well as prospective practical applications. A topological insulator is a material that behaves like an insulator in its interior but whose surface contains conducting states. For example, electrical insulators in bulk are able to conduct electrons extremely well at the surface. They are also an example of a ‘topological phase of matter', the discovery of which earned physicists the Physics Nobel Prize in 2016.

 

Dr Siu is currently a Research Fellow at the Computational Nanodevices and Nanoelectronics Laboratory at the NUS Electrical and Computer Engineering (ECE) department. He completed his B.Sc. (Hons) and M.Sc. at the Department of Physics in 2008 and 2010, respectively. Thereafter, he pursued his Ph.D. at NUS Graduate School at the ECE department, from 2010 to 2015.
