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.

通过金属吸附调节单层MoSe _2中的电子和磁性

我们通过第一性原理计算系统地研究了金属Pd，Pt，Cu，Ag，Au和Zn吸附的MoSe ₂单层的电子结构和磁性。这表明在吸附原子Pd，Pt，Cu，Ag，Au和MoSe ₂单层之间已经形成了稳定的化学吸附，但是由于吸附能量小，Zn和MoSe ₂单层之间发现了较弱的物理相互作用。吸附金属的MoSe ₂单层的骨架结构和电子性质都通过吸附原子进行了微调。更重要的是，在铜，银和金系统中引入了磁特性。
