| Abstract: | Under external transverse electronic fields, the structure and electronic properties of the silicene nanoribbon with armchair edge (ASiNR) are studied. We find that the electric properties are modified by a transverse electric field. As affected by a transverse electric field, the band gap varies with increasing absolute value of the field strength. All the results can be explained using the Stark quadratic effect. |
