    Point-like vacancies in two-dimensional transition metal dichalcogenides
    (Institute of Physics, 2024) Özcan, Sibel; Gallardo, Aurelio; Biel, Blanca
    his study explores the realm of two-dimensional transition metal dichalcogenides (TMDs), examining some of the most prevalent defects. Employing density functional theory, we scrutinize three common defect types across four extensively studied TMDs: MoS2, MoSe2, WS2, and WSe2. Our investigation spans the energetics of these defects, unveiling the most stable ones, and unraveling the alterations in structural and electronic properties induced by their presence. As a further step towards practical applications, we simulate the images that would be captured by both Atomic and Kelvin Probe Force Microscopes, aiming at a facile identification of these defects when probed at the microscopic level.
