Organic tunnel field-effect transistors

, 2023
Abstract The much sought after intrinsically flexible organic transistors are poised to become a central ingredient in the development of wearable technologies and bioelectronics1-3. A paramount requisite for these applications lies in achieving high signal amplification at low power.

Generation of STDP With Non-Volatile Tunnel-FET Memory for Large-Scale and Low-Power Spiking Neural Networks

IEEE Journal of the Electron Devices Society, 2020
Spiking neural networks (SNNs) have attracted considerable attention as next-generation neural networks. As SNNs consist of devices that have spike-timing-dependent plasticity (STDP) characteristics, STDP is one of the critical characteristics we need to

Silicon spin diffusion transistor: materials, physics and device characteristics

, 2005
The realisation that eaveryday electronics has ignored the spin of the carrier in favour of its charge is the foundation of the field of spintronics. Starting with simple two-terminal devices based on GMR and tunnel magnetoresistance, the technology has ...

Sub-10nm tunnel field-effect transistor with graded Si/Ge heterojunction

, 2011
This study presents a new sub-10-nm tunnel field-effect transistor (TFET) with bandgap engineering using a graded Si/Ge heterojunction. Both the height and width of the tunneling barrier are highly controlled by applying gate voltages to ensure a near ...

Drain Current Model for Double Gate Tunnel-FETs with InAs/Si Heterojunction and Source-Pocket Architecture

Nanomaterials, 2019
The practical use of tunnel field-effect transistors is retarded by the low on-state current. In this paper, the energy-band engineering of InAs/Si heterojunction and novel device structure of source-pocket concept are combined in a single tunnel field ...

Simulation of Dual-Material Hetero-Double Gate Tunnel Field Effect Transistor (TFET) in Sub-Micron Region

Journal of Engineering Technology and Applied Physics, 2023
To meet the performance requirements of low power mobile devices, a device with a high ION/IOFF ratio at low-VDD is needed. TFETs are gaining popularity due to their low subthreshold slope and high transconductance compared to MOSFETs.

Uniform Strain in Heterostructure Tunnel Field-Effect Transistors [PDF]

IEEE Electron Device Letters, 2016
Strain can strongly impact the performance of III–V tunnel field-effect transistors (TFETs). However, previous studies on homostructure TFETs have found an increase in ON-current to be accompanied with a degradation of subthreshold swing. We perform 30-band quantum mechanical simulations of staggered heterostructure p-n-i-n TFETs submitted to uniaxial ...

Tunnel field-effect transistor without gate-drain overlap

, 2007
Tunnel field-effect transistors are promising successors of metal-oxide-semiconductor field-effect transistors because of the absence of short-channel effects and of a subthreshold-slope limit.

Tunnel field-effect transistors with graphene channels

, 2022
S.279-284The lack of an OFF-state has been the main obstacle to the application of graphene-based transistors in digital circuits. Recently vertical graphene tunnel field-effect transistors with a low OFF-state current have been reported; however, they ...

Configurable Electrostatically Doped High Performance Bilayer Graphene Tunnel FET

IEEE Journal of the Electron Devices Society, 2016
A bilayer graphene-based electrostatically doped tunnel field-effect transistor (BED-TFET) is proposed. Unlike graphene nanoribbon TFETs in which the edge states deteriorate the OFF-state performance, BED-TFETs operate based on bandgaps induced by ...
