“…Some researchers have used the Mott's relation to obtain the thermopower, [62,63] and some are estimating the electrical conductivity and thermopower by College of Engineering, State University of New York Polytechnic Institute, Albany, NY, 12203, USA. *E-mail: tangs1@sunypoly.edu (S. Tang) using a constant relaxation time approximation or by only considering the acoustic phonon scattering, [64][65][66] despite of the significant deviation from the real values. A more accurate method has been developed recently by Tang et al, [67,68] by using the energy sensitivity of carrier transport and transport rate coefficient extracted from the experimental measurement.…”

With the development of micro and mesoscale electronics, photonics and optoelectronics, the heat management in such small scales are becoming important. In several emergent areas such as quantum computing and communication, satellite controlling and sensing, the overall refrigeration or cooling rate is having a priority over the energy consumption efficiency. Beyond the passive heat draining, active solid-state refrigeration and cooling based on the Peltier effect have been attractive. We are here suggesting the materials system of carbon nanotubes. By incorporating the energy sensitivity of transport into the thermopower investigation, we have found that the active refrigeration and cooling rates are better than or as least similar to the thermal conductivity of commonly used functional metals, especially at and above the room temperature. The performance is also robust against the fluctuation of band gap introduced during the batch synthesis of carbon nanotubes. Furthermore, the p-and n-type regions have similar performance in thermoelectric refrigeration and cooling, which is providing convenience for the ultimate device design and manufacturing.

“…Silicene also can be grown on a non-metallic aluminum substrate of Al2O3 that maintains the structural profile of low-buckled honeycomb lattice [22]. More recently, the graphene [23] and the silicane [24] substrates have also been studied. Numerous articles have worked on the electrical properties of silicene and examined the effects of electric and magnetic fields on the electrical properties of silicene [25][26][27].…”

Silicene, a zero-gap semi-metallic advanced material, has received much attention due to its extraordinary electronic and optical characteristics, which could be used in plasmonics nano-devices. This material presenting as a tunable material without degrading its high carrier mobility. By applying the rigorous numerical techniques, the optical and electrical properties of silicene at high terahertz frequencies are calculated here. Beneath the inﬂuence of environmental effects such as the Fermi level, temperature, and external electric field, on the optical conductivity and refractive index of silicene are investigated using the tight-binding model. The effect of Fermi level from zero to 1 eV, external electric field from zero to 2.5 eV, and temperature from 5 to 400 K are investigated on the optical properties of silicene. One of the interesting features of Silicene is its adjustable bandgap, which we are present here.
