SPS Alumni Talk by Dr Siu Zhuo Bin

Featuring Dr Siu Zhuo Bin from SPS 2004, the second edition of SPS alumni talk this year was held on 1 March 2017. Zhuo Bin completed his BSc (Hons) and MSc at the Department of Physics from 2004 to 2008, and 2008 to 2010 respectively, and his PhD at the NUS Graduate School at the Department of Electrical and Computer Engineering (ECE) from 2010 to 2015. He is currently a Research Fellow at the Computational Nanodevices and Nanoelectronics Laboratory at the NUS ECE department. His research interest is 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.

Topological insulators (TIs) are emerging class of materials which have attracted widespread interest due to their fascinating properties from both the fundamental physics as well as prospective practical applications points of view. For example, electrical insulators when considered as a bulk, these materials are able to conduct electrons extremely well at the surface. They are also one example of a `topological phase of matter', the discovery of which earned the key workers in the field the Physics Nobel Prize in 2016. In his talk, Zhuo Bin gave an introduction to topological insulators from the perspective of a computational physicist working in the Faculty of Engineering. TIs illustrate how abstract mathematics, condensed matter physics, and engineering could come together to form an interdisciplinary research at the interface between science and engineering.
