Research Fellow (Condensed Matter Physics-Experimental Studies of Epitaxial Moiré Superstructures)

The successful candidate will work with Associate Professor Wang Xuesen & Professor Wee Thye Shen, Andrew on experimental studies of epitaxial moiré superstructures under a project on the Investigation of Practical Epitaxial Moiré Superstructures with Novel Electronic Properties.

The main responsibilities of the position include:

• To identify several overlayer-substrate material combinations suitable for epitaxial moiré superlattices
• To carry out epitaxial growth of the overlayer that forms a moiré superlattice on a substrate in ultrahigh vacuum (UHV) chamber
• To analyze the atomic and electronic structures of epitaxial moiré superlattices using scanning tunneling microscopy and spectroscopy (STM/STS)
• To analyze experimental data, comparing with computational results and draft manuscripts for publication
• To provide guidance and assistance to the PhD and Master students doing similar experimental studies in this project.

• Qualifications / Discipline:  PhD degree in Physics, Chemistry or Materials Science.

• Skills:  Have a comprehensive understanding of the novel physical properties of material structures based on various 2D materials;  Capable of using UHV sample preparation and film growth facilities to fabricate the epitaxial moiré superstructures, especially those made of Group-V (Sb, Bi, P) and Group IV-VI compounds (e.g., GeS, GeSe, SnS, and SnSe);  Capable of in situ STM/STS analysis of the atomic and electronic structures of epitaxial moiré superstructures; Skills of performing LEED, XPS and ARPES analysis are also desirable; Strong skill of writing and oral communication in English. 

• Experience:  Has at least 4 years of:  1) Using Omicron UHV LT-STM systems for surface, nanostructures and thin film investigations; 2) surface cleaning, atomic layer and film deposition, especially involving materials of Group-V (Sb, Bi, P) and Group IV-VI compounds (e.g., GeS, GeSe, SnS, and SnSe); 3) UHV and low-temperature STM/STS analysis of the atomic and electronic structures of surfaces, thin films and nanostructures.  Experience of LEED, XPS and ARPES analysis is also desirable.
