Nano carbon devices are promising for the next generation devices. Recently, a single-layer graphene has also been developed as nano-devices. For the device applications, there are several reasons why we should control the noise. Of course, the reduction of noise is one of strategies for nano devices as the noise might be increases for nano size devices including Si devices. On the other hand, noise...
On the recent developments in nano devices, carbon nanotube (CNT) is one of the candidates for next generation devices. For device applications, it might be the problem that CNTs show large noise because of large surface area. However, sometimes nonlinear systems have advantages in the working with noise. In stochastic resonance (SR), noise could enhance the working properties of devices. Therefore,...
Stochastic resonance (SR) in carbon nanotube field-effect transistors (CNT-FETs) was investigated to enhance their weak-signal response. When weak pulse trains were applied to the gate of a CNT-FET operating in a subthreshold regime, the correlation coefficient between the input and output voltages increased upon addition of noise with optimized intensity. SR was observed both in air and in solutions...
