The Effects of Heteroatom Adsorption on the Electronic Properties of Phosphorene

Figure 4

(a) Charge densities of Li adatoms on phosphorene [17]. (b) Phase I [18] and (c) phase II of Li doped phosphorene, the difference at −1.5 eV below the Fermi level: phase I possesses a smaller gap (SG) whereas phase II has a larger gap (LG) [18]. (d) DOSs of phosphorene adsorbed with Li-Mg adatoms [17].
