Symmetry-breaking-dependent electronic structures and strain regulation in ReSeS monolayer

Electronic devices for information storages and processes can be further optimized by introducing the degree of freedom of anisotropy, which is strongly dependent of their structural symmetry. Herein, a ReSeS monolayer with asymmetrical double-faces are proposed to disclose the anisotropic electronic structure. Meanwhile infrared fingerprint based on the lattice vibration is also adopted to demonstrate the symmetry-breaking-dependent structural transformation. First-principles calculations demonstrate that the geometry deformation will induce the reconstruction of electronic structure. Ulteriorly, both the dynamic properties of carrier and spectroscopic response can be regulated by external strain and displays anisotropic behaviors. Our idea provides threads for designing new regulable optoelectronic devices.
Comment: At present, the calculations and interpretations of defect properties, Raman spectroscopic properties, and electronic effective masses involved in this paper are unreliable
