We study electrical modulation of transport properties silicene nanoconstrictions with different geometrical structures. investigate the effects position and width central scattering region on conductance increasing Fermi energy. It is found that significantly depends nanoconstriction. Interestingly, symmetrical structure constriction can induce a resonance effect increase systemʼs conductance....

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...
