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 […]
In this paper, the electrical characteristics and sensitivity analysis of staggered type p-channel heterojunction electron-hole bilayer tunnel field effect transistor (HJ-EHBTFET) are thoroughly investigated via simulation study. The minimum lattice mismatch between InAs/GaAs0.1Sb0.9 layers besides low carrier effective mass of materials provides high probability of tunneling current that eventually boosts the device performance. Unlike the […]
Drain conductance to drain current ratio is analytically investigated for junctionless accumulation mode MOSFET in presence of ultrathin buried oxide layer invoking the effect of conduction band tunnelling, within realistic range of dimensional configurations in nano regime. By taking into account the flatband voltage’s influence and the image charge effect at the oxide-semiconductor interface, subthreshold […]
