Abstract: Van der Waals crystals provide a promising material platform for the development of next generation two-dimensional semiconductors (2SEM). Here, I will review my research on 2SEM based on metal chalcogenides and present a unique-in-the world facility (EPI2SEM, https://bit.ly/3zN00dx) for the EPItaxial growth and in situ analysis of 2SEM.
EPI2SEM consists of a custom-designed reactor for molecular beam epitaxy (MBE) whose ultra-high vacuum (UHV) operation matches the UHV requirements for in situ analytical techniques, such as SPM (scanning probe microscopy) and nanoESCA (nanoscale electron spectroscopy for chemical analysis). By integration of growth, advanced microscopy and spectroscopy in UHV, EPI2SEM is used to create atomically thin semiconductors with engineered physical properties beyond the current state-of-the-art, including wafer-scale 2SEM for deep UV sensing.

Brief CV: Amalia Patanè studied at the University of Rome “La Sapienza” where she received her MSc in Physics (1994) and PhD (1998). She then moved to the School of Physics and Astronomy at Nottingham where she has been Professor of Physics (since 2011) and Director of Research (2019-23). Her research achievements in semiconductor physics were recognized by the Sir Charles Vernon Boys Medal and Prize of the Institute of Physics (2007), an EPSRC Advanced Research Fellowship (2004-09), a Leverhulme Trust Research Fellowship (2017-19), a Chinese Academy of Science (CAS) President’s International Fellowship Award (2018-19), and an honorary professorship at the Institute of Semiconductors, CAS, Beijing. Since 2015, Patanè is the UK Director and Council member of the European Magnetic Field Laboratory to support the development and use of high magnetic field facilities for science and technologies. Also, she leads at Nottingham EPI2SEM for the EPitaxial growth and In-situ analysis of 2-dimensional SEMiconductors (https://bit.ly/3zN00dx).
