The point defects in monolayer InSe. The black circles illustrate the position of defects. Defects are called (a) single selenide vacancy (VSe1), (b) single indium vacancy (VIn1), (c) diselenide vacancy (VSe2), (d) diindium vacancy (VIn2), (e) vacancy of double InSe pair (VInSe2), (f) vacancy of In and nearby three Se atoms (V3Se1In), (g) vacancy of Se and nearby three In atoms (V1Se3In), (h) vacancy complex of In and nearby three Se pairs (V6Se2In), (k) vacancy complex of Se and nearby three In pairs (V2Se6In).
