This month it was our pleasure to host Antonio di Bartolomeo, who is currently full professor and president of the Physics Education Committee of the Department of Physics of the University of Salerno. His research focuses on optical and electrical properties of graphene, transition metal dichalcogenides, carbon nanotubes, composite and 2D layered materials as well as semiconductor heterojunctions and their application as photodetectors, solar cells, and chemical sensors among other things.
In his talk on “Electrical conduction and photoconduction in 2D materials based transistors” he gave insights into his research, investigating the electrical transport and the photoresponse of 2D transition metal dichalcogenides (TMDs) such as MoS2, ReS2, and PtSe2 as a function of temperature and pressure. Discussing several aspects of electrical transport observed in 2D materials, he emphasizes the key role that intrinsic defects and adsorbates have in pressure- and temperature-dependent photoresponse.
As a result of an ongoing close collaboration, the two working groups of Prof. Antonio di Bartolomeo and our PI Prof. Marika Schleberger have recently published a new paper on the “Manipulation of the electrical and memory properties of MoS2 field-effect transistors by highly charged ion irradiation”. Among others our 2D-MATURE PhD student Osamah Kharsah and associated researcher André Maas are involved.

Thank you, Prof. di Bartolomeo, for the great talk. We are looking forward to continue working together.
