In September, our team published an article devoted to fundamental research into a new class of materials that have the potential to make a significant contribution to the development of modern microelectronics. We are talking about the so-called transition metal dichalkogenides, from which we have selected platinum diselenide (PtSe2) as the representative material.

In this article, we focused on the morphological studies of the influence of the surface preparation procedure on the PtSe2 substrate. We show that mechanical exfoliation is one of the possible ways to obtain a clean PtSe2 surface. Thanks to the STM measurements, we were also able to conclude that this process is insufficient to obtain an atomically clean surface.
