Novel attributes of steep-slope staggered type heterojunction p-channel electron-hole bilayer tunnel field effect transistor

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 ...

Switching Performance of Nanotube Core-Shell Heterojunction Electrically Doped Junctionless Tunnel Field Effect Transistor

Abstract: In this paper, a novel tunnel field effect transistor (TFET) is introduced, thatdue to its superior gate controllability, can be considered as a promising candidate forthe conventional TFET. The proposed electrically doped heterojunction TFET(EDHJTFET) has a 3D core-shell nanotube structure with external and internal gatessurrounding the channel that employs el...

Performance Study and Analysis of Heterojunction Gate All Around Nanowire Tunneling Field Effect Transistor

In this paper, we have presented a heterojunction gate all around nanowiretunneling field effect transistor (GAA NW TFET) and have explained its characteristicsin details. The proposed device has been structured using Germanium for source regionand Silicon for channel and drain regions. Kane's band-to-band tunneling model hasbeen used to account for the amount of band-to...

Valence band alignment and hole transport in amorphous/crystalline silicon heterojunction solar cells

To investigate the hole transport across amorphous/crystalline silicon heterojunctions, solar cells with varying band offsets were fabricated using amorphous silicon suboxide films. The suboxides enable good passivation if covered by a doped amorphous silicon layer. Increasing valence band offsets yield rising hole transport barriers and reduced device effciencies. Carrier transport by thermal ...
