Computational study plays an important role to discover the potential of the bio-inspired nano scale molecular devices. Density Functional Theory (DFT) is one of the popular methods to calculate the properties of the molecules which can not be possible with ab initio process, preferably for transition metals. This method is important for electronic structure calculation […]
The p-i-n carbon nanotube (CNT) devices suffer from low ON/OFF current ratio and small saturation current. In this paper by band bending engineering, we improved the device performance of p-i-n CNT field effect transistors (CNTFET). A triple gate all around structure is proposed to manage the carrier transport along the channel. We called this structure […]
Emerging trend in semiconductor nanotechnology motivates to design various crystalline nanotubes. The structural and electronic transport properties of single walled zigzag Gallium Arsenide nanotubes have been investigated using Density Functional Theory (DFT) and Non-Equilibrium Green’s Function (NEGF) based First Principle formalisms. Structural stability and enhanced electronic transmission property of Gallium Arsenide nanotubes (NT’s) have been […]
In this paper, we present a new self-switching diode (SSD) realized with a two-dimensional semiconductor hexagonal boron carbon-nitrogen (hBCN) monolayer. Channel length and width are 4.5 nm and 1.23 nm respectively. The device operation is simulated based on the Extended Huckel method and Nonequilibrium Green’s Function (NEGF) Formalism. The simulation results indicate non-linear I-V characteristics […]
