Researchers modify MoS2 monolayer to control light and charge
An interdisciplinary team from the National Research Council (CNR) and the University of Florence has successfully modified molybdenum disulfide (MoS2) at the atomic level. The research, published in the journal Nano Letters, demonstrates how a material only one atom thick can be engineered to retain electrical charge for extended periods and modulate light emission.
The breakthrough relies on the precise manipulation of sulfur vacancies—tiny defects within the material's atomic structure. Using an electrochemical nanolithography technique developed by the research group, scientists were able to introduce and distribute these defects with sub-micrometric precision. This controlled arrangement allows the monolayer to function as a form of electrostatic memory.
This advancement in two-dimensional (2D) materials offers significant potential for the development of next-generation optoelectronics, high-capacity batteries, and advanced functional surfaces. The study was conducted as part of the PRIN MAVAM project, supported by the Italian Ministry of University and Research (MUR) and the European Union through the Next Generation EU program.
