Abstract:
The electro-optical (EO) device is a subject of main concern in modern science and technology. In this regard, the molecular optical switch based on DNA sequence of the Toxocara canis parasite has been designed. To reach this goal, based on theoretically studied, we have put DNA between two leads and have connected to a voltage source. The obtained result show that when the amplitude and frequency of incident light reach to A_0≈0.3 ћc/(ier_0 ) and ω≈1 THz, respectively, switch turns on. We can adjust the switching behavior of the system by simultaneous varying the effective factors such as amplitude and frequency of incident light and temperature and external bias voltage which obtain different islands in parameter settings. We have found the on/off states of electrical current that can be confirmed by multi-fractal analysis. Therefore, one can design and modulate an optical switch based on DNA chains. Such a molecular switch can be used in future nanoelectronic devices.
