The structural, magnetic and electronic properties of p-type and n-type doped monolayer WS2 systems

(a) The top and (b) side views of the monolayer WS2 system doped with a single nonmetal atom X (X=N, P, As, Sb, Cl, Br, I or At), where the gray, yellow and red balls represent W, S and X atom, respectively. (c) The trigonal prismatic coordination of the W atom. (d) The spin- polarized band structures and (e) the total density of states (DOS) of pristine monolayer WS2 system.191
