The Effects of Substrate Phonon Mode Scattering on Transport in Carbon Nanotubes [PDF]

, 2008
Carbon nanotubes (CNTs) have large intrinsic carrier mobility due to weak acoustic phonon scattering. However, unlike two-dimensional metal-oxide-semiconductor field effect transistors (MOSFETs), substrate surface polar phonon (SPP) scattering has a ...

Study of CNTFETs as Memory Devices

ECS Journal of Solid State Science and Technology, 2022
In this paper we propose a procedure for the study of CNTFETs as memory devices. In particular we analyze the design of a 6-T SRAM, in order to evaluate the writing and reading times, in single and double supplies, the static noise margin, the static power consumption and the power-delay product. For these goals, we use a CNTFET model, already proposed

Synaptic Characteristics of Fully Depleted Silicon‐on‐Insulator Metal‐Oxide‐Semiconductor Field‐Effect Transistors and Synapse‐Neuron Arrayed Neuromorphic Hardware System

Advanced Intelligent Systems, Volume 6, Issue 6, June 2024.
Fully depleted silicon‐on‐insulator (FDSOI) field‐effect transistor (FET) is demonstrated as for artificial synapse, where FDSOI substrate mitigates leakage current and low power when compared to bulk Si. To validate stable hardware interactions, 5 × 6 synapse arrays using these verified FDSOI FETs are interconnected to 10 × 10 LIF neuron arrays.

Fast Nitrogen Dioxide Sensing with Ultralow‐Power Nanotube Gas Sensors

Advanced Sensor Research, Volume 3, Issue 1, January 2024.
This work presents a fast and ultralow‐power NO2 sensor that uses an individual carbon nanotube as its sensing material. The study reports significantly improved recovery and readout times of 1–5 min and limit of detection below 10 ppb, while maintaining carbon nanotube's known advantage in power consumption (peak power below 10 microwatts).

Sensitive Detection of a Gaseous Analyte with Low‐Power Metal–Organic Framework Functionalized Carbon Nanotube Transistors

Advanced Electronic Materials, Volume 10, Issue 1, January 2024.
Outstanding performance in detecting ethanol molecules at sub‐ppb concentrations is achieved by integrating large‐diameter carbon nanotube field‐effect transistors with a metal–organic framework layer. These sensors operate with extremely low power consumption in the picowatt range and exhibit insensitivity to ambient humidity conditions, positioning ...

An Efficient Approximate Multiplier with Encoded Partial Products and Inexact Counter for Joint Photographic Experts Group Compression

IET Circuits, Devices &Systems, Volume 2024, Issue 1, 2024.
Approximate computing is commonly employed in applications where accuracy is not crucial and aims to enhance circuit performance when inaccurate results are not challenging. The multipliers are power‐hungry, and their approximation has been the target of research, especially by using approximate counters.
