Electronic structure and electrical conductance properties of two-dimensional arsenin

Arsenene is one of the members a large group two-dimensional structures that in present project, we have investigated single layer structure and its nanoribbons based on density functional theory. In this study, after calculating band structure, discussed effect width nanoribbon from angle quantum limiting phenomenon. The results show different phenomenon points each which cause indirect-direct gap transition due to reduction armchair nanoribbon. Also, electrical conductance properties arsenene been obtained by mobility load carriers uniaxial strain crystalline them has investigated. order investigate mobility, defects neglected only phonon dispersion considered Takagi relationship. process, focus not quantitative accuracy values for existing anisotropy between two directions zigzag discussion. calculations significant crystal it. difference electrons holes direction key results.
