Switching behaviour of stilbene molecular device: a first-principles study
The switching behaviour of stilbene molecular system (SMS) device is investigated with the help of non-equilibrium Green’s function (NEGF) approach using first principles calculation. The transmission spectrum of cisisomers confirmed that more electrons are transferred across the SMS-device using op...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | The switching behaviour of stilbene molecular system (SMS) device is investigated with the help of non-equilibrium Green’s function (NEGF) approach using first principles calculation. The transmission spectrum of cisisomers confirmed that more electrons are transferred across the SMS-device using optical excitation by the
spin of C=C bond by torsion angle (θ = 180◦
). The current-voltage characteristics show the lower magnitude
of current for trans-stilbene and higher magnitude of current for cis-stilbene for an externally applied bias
voltage. The outcome of the proposed work suggests that cis and trans-stilbene molecular device can be used
as a switch. |
