“…The expansion of each term including transmittance and CP on the above equations (3.1) and (3.2) is clearly discussed in our previously reported work [1,30] If V b is set to zero voltage, the transmission energy at Fermi level T(E F ) provides the conductance G = G 0 T(E F ), where G 0 = (2e 2 )/h is the unit of quantum conductance [29,47]. The orbital delocalization along the stilbene molecular system directs to enhance the concentration of free electrons, where it is noticed on particular peak amplitudes P amp in the transmission spectrum of SMS device [48][49][50][51]. The conductance G is explored for various lengths of Au-electrodes.…”
