Job Description
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
• 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.
