摘要：
We have systematically explored the electronic structures and magnetic properties of metal Pd, Pt, Cu, Ag, Au and Zn adsorbed MoSe2 monolayer by means of first-principles calculations. It reveals that stable chemical adsorption has been formed between the adatoms Pd, Pt, Cu, Ag, Au and MoSe2 monolayer, however, weak physical interaction is found between Zn and MoSe2 monolayer owing to the small adsorption energy. Both the framework structure and electronic property of the metal adsorbed MoSe2 monolayer are slightly tuned by the adatoms. More importantly, magnetic character is introduced in Cu, Ag and Au systems. (C) 2017 Elsevier B.V. All rights reserved.
