TLDR
Tunnels based on ultrathin semiconducting films or nanowires could achieve a 100-fold power reduction over complementary metal–oxide–semiconductor transistors, so integrating tunnel FETs with CMOS technology could improve low-power integrated circuits.
Abstract
Power dissipation is a fundamental problem for nanoelectronic circuits. Scaling the supply voltage reduces the energy needed for switching, but the field-effect transistors (FETs) in today's integrated circuits require at least 60 mV of gate voltage to increase the current by one order of magnitude at room temperature. Tunnel FETs avoid this limit by using quantum-mechanical band-to-band tunnelling, rather than thermal injection, to inject charge carriers into the device channel. Tunnel FETs based on ultrathin semiconducting films or nanowires could achieve a 100-fold power reduction over complementary metal-oxide-semiconductor (CMOS) transistors, so integrating tunnel FETs with CMOS technology could improve low-power integrated circuits.

Building Brain-Inspired Logic Circuits from Dynamically Switchable Transition-Metal Oxides

TL;DR: In this article, the authors review current understanding of the mechanisms underpinning electronic instabilities, discuss methods for modulation of spiking behavior through tuning of atomistic and electronic structure, and highlight the need for establishing deterministic and independent control of transformation characteristics such as switching magnitude, energy thresholds, heat dissipation, hysteresis and dynamics of relaxation.

Prospects of Hysteresis-Free Abrupt Switching (0mV/dec) in Landau Switches

TL;DR: In this paper, the authors provide an intuitive classification of all charge-based switches in terms of their energy landscapes and identify two-well energy landscape as the characteristic feature of Landau switches and conclude that a flat energy landscape is essential for hysteresis-free abrupt switching.

Use of Negative Capacitance to Provide Voltage Amplification for Low Power Nanoscale Devices

TL;DR: By replacing the standard insulator with a ferroelectric insulator of the right thickness it should be possible to implement a step-up voltage transformer that will amplify the gate voltage thus leading to values of S lower than 60 mV/decade and enabling low voltage/low power operation.

Double-Gate Tunnel FET With High- $\kappa$ Gate Dielectric

TL;DR: In this article, a double-gate tunnel field effect transistor (DG tunnel FET) with a high-kappa gate dielectric was proposed and validated using realistic design parameters, showing an on-current as high as 0.23 mA for a gate voltage of 1.8 V, an off-current of less than 1 fA (neglecting gate leakage), an improved average sub-threshold swing of 57 mV/dec, and a minimum point slope of 11 mV /dec.

A theory of the electrical breakdown of solid dielectrics

TL;DR: In this paper, two distinct mechanisms have been suggested for the sudden increase of the number of electrons in an unfilled band, which occurs when the field strength passes a critical value, analogous to the electrical breakdown of gases.
