Research Fellow in The Electronic Properties of

**The Opportunity**

The study of twisted heterostructures of two-dimensional (2D) materials such as graphene is an exciting fast-moving field at the forefront of condensed matter physics and nanoscience, with vast opportunities for tailoring the properties of interacting electrons in 2D to produce new phenomena such as superconductivity and topological phases, as well as potentially useful electronic devices. We are seeking to appoint a Postdoctoral Research Fellow in the area of experimental condensed matter physics and surface science to study the electronic properties of 2D twisted heterostructures of atomically thin semiconductors (e.g. MoS2, WS2), a relatively unexplored but promising new area of 2D heterostructure science.
- Conduct research into the electronic properties of twisted two-dimensional semiconductor heterostructures using micro
- and nano-angle-resolved photoemission spectroscopy
- Publish research outcomes in high-impact peer-reviewed journals, contribute to high-profile conferences and workshops
- Assist in the supervision of MSc and PhD students

The successful applicant must hold a PhD in experimental condensed matter physics or a closely related field. Experience with angle-resolved photoemission spectroscopy and x-ray photoelectron spectroscopy is essential. Experience in fabrication of van der Waals heterostructures of 2D materials (i.e. exfoliation and controlled positioning and stacking of 2D materials), along with lithographic techniques for device fabrication, and synchrotron experience are highly desirable.

In addition to having the primary responsibility for angle-resolved photoemission spectroscopy, the Research Fellow will work as part of a larger team that is tasked with characterising the electronic structure of twisted semiconductor heterostructures using low-temperature scanning tunnelling microscopy and electronic transport measurements.

**Environment**

The position is funded by an ARC Discovery Project with chief investigators Dr Mark Edmonds and Professor Michael Fuhrer in the School of Physics and Astronomy at Monash University.

The School provides a vibrant environment for research in Experimental Condensed Matter Physics and Nanoscience, and it is committed to further increasing the number of researchers in this area. World-class experimental science is a high priority in the School’s Strategic Plan. The School’s research infrastructure includes the Monash Centre for Atomically Thin Materials and the ARC Centre of Excellence for Future Low-Energy Electronics Technologies (FLEET), directed by ARC Laureate Fellow Professor Michael S. Fuhrer. The School is an active user of synchrotron radiation facilities, including the Australian Synchrotron, which is located adjacent to the Clayton campus of Monash University. The School has access to state-of-the-art facilities in the Melbourne Centre for Nanofabrication, which is adjacent to the Australian Synchrotron at the Clayton campus. The School’s research laboratories were recently moved to a $175M building - the New Horizons Centre.

Dr Mark Edmonds is a Lecturer in the School of Physics & Astronomy at Monash University. He is an associate investigator in the ARC Centre of Excellence in Future Low-Energy Electronics Technologies (FLEET) and investigator in the Monash Centre for Atomically Thin Materials (MCATM). He leads a laboratory and research group into the growth via molecular beam epitaxy of novel electronic materials such as topological Dirac semimetals and topological insulators and their electronic properties. The laboratory includes state-of-the-art facilities for growth via molecular beam epitaxy and in-situ diffraction characterisation in ultra-high vacuum, with a glove box attached to the load lock. An ultra-high vacuum suitcase allows transfer of samples to the Toroidal Analyser at the Australian Synchrotron for angle-resolved photoelectron spectroscopy measurements. High magnetic field cryostats are also available for sample characterisation. Further information on Dr Edmonds research programme is available at: research.monash.edu/en/persons/mark-edmonds.

Professor Michael Fuhrer is a Professor and former ARC Laureate Fellow in the School of Physics and Astronomy. Fuhrer runs a vigorous experimental research program on graphene, atomically thin semiconductors, and topological materials. Fuhrer’s laboratory in the New Horizons Centre is equipped with two low-temperature (4.5 K) ultra-high vacuum scanning tunnelling microscopes, low-temperature electronic measurement facilities (
