Interfacial charge-modulated carbon nanotube FET with a WS2 nanosheet sensing layer for room-temperature H2S detection
Hydrogen sulfide (H2S) leakage is a critical threat to industrial safety, environmental monitoring, and human health, yet low-power detection of low-concentration H2S at room temperature remains challenging because gas-adsorption-induced electrical signals are typically weak and susceptible to environmental interferenc...

Zinc Oxide/Ag Water-Gated Field-Effect Transistor Coupled with Surface-Enhanced Raman Scattering for Indigo Dye Detection
Water-gated field-effect transistors (WGFETs) based on a solution-processed ZnO–Ag composite are developed as a complementary electrical–spectroscopic sensing platform, combining electrical detection of indigo in aqueous media with SERS-based molecular identification on the same ZnO–Ag active layer. The resulting WGFET...

A Charge-Based Analytical Model for MgZnO/ZnO MOS-HEMT Biosensor
In this work, we have developed a physics-based analytical framework for a dielectric-modulated MgZnO/ZnO MOS-HEMT biosensor that can detect the biomolecules. Biomolecule dielectric modulation is linked with effective gate capacitance, 2-DEG density, surface potential, and drain current. The analytical baseline MgZnO...

Research on electrical performance enhancement of carbon nanotube MOSFETs based on thermal annealing optimization
Carbon nanotube thin-film transistors (CNT-TFTs), owing to their exceptional carrier transport properties and stable quasi-one-dimensional structure, are widely recognized as ideal candidates for next-generation nano-electronic devices. However, the practical performance of CNT-based devices is often limited by the int...

MoS2-decorated graphene gate AlGaN/GaN/AlN HEMTs for highly selective hydrogen gas sensor
Hydrogen is widely acknowledged as a potentially useful clean energy carrier. A high degree of selectivity in sensing systems are required to ensure its safe deployment. This research aims to propose a H2 gas sensor that demonstrates a high degree of selectivity using a MoS2-decorated graphene-gated AlGaN/GaN high...
