Role of Potential barrier in Nanowire

Theoretical investigation has been performed on electron transport properties of 4, 4 - diamino biphenyl based molecules that is sandwiched between two gold surfaces. Dependence of the molecular electronic structure of the gold–molecule complex on the external electric field is studied too. . According to Systematic study on the molecular orbital populations, six member hetero-aromatic rings (electron-rich) in the conduction path are inserted between the donor–donor complexes. Values of Potential barrier (PB) that have been determined experimentally and reached the conclusion is mentioned later in this paper.
