Abstract
In this article, we investigated the sensitivity of the junctionless silicon nanotube tunnel field-effect transistor (JLSiNT-TFET). To accomplish this, we utilized the Sentaurus TCAD software tool to generate the 3D JLSiNT-TFET device. The sensitivity analysis is conducted using the device’s geometrical parameters, including channel length (Lg), dielectric oxide (Tox) thickness, and silicon (tube wall) thickness (Tsi). This analysis is based on various device metrics, such as ON current (ION), OFF current (IOFF), sub-threshold swing (SS), threshold voltage (Vth), and cut-off frequency (fT). We observed that increasing the gate length (Lg) and tube wall thickness (Tsi) leads to sensitivity in ION, SS, and fT for larger values, while these parameters exhibited lower sensitivity to IOFF and Vth. Furthermore, when the dielectric oxide thickness (Tox) increased, we noted an increase in the sensitivity of IOFF current, accompanied by a decrease in ION and fT. Comparing the proposed device to the SiNT-TFET, we found significant improvements: ION improved by 39.51%, the ION/IOFF ratio increased by 40%, transconductance (gm) rose by 28.47%, and fT surged by 94.81%. Finally, the JLSiNT-TFET device metrics confirmed that substantial superiority over the silicon nanotube tunnel field-effect transistor (SiNT-TFET).
期刊介绍：
The objective of the Journal of Nanoparticle Research is to disseminate knowledge of the physical, chemical and biological phenomena and processes in structures that have at least one lengthscale ranging from molecular to approximately 100 nm (or submicron in some situations), and exhibit improved and novel properties that are a direct result of their small size.
Nanoparticle research is a key component of nanoscience, nanoengineering and nanotechnology.
The focus of the Journal is on the specific concepts, properties, phenomena, and processes related to particles, tubes, layers, macromolecules, clusters and other finite structures of the nanoscale size range. Synthesis, assembly, transport, reactivity, and stability of such structures are considered. Development of in-situ and ex-situ instrumentation for characterization of nanoparticles and their interfaces should be based on new principles for probing properties and phenomena not well understood at the nanometer scale. Modeling and simulation may include atom-based quantum mechanics; molecular dynamics; single-particle, multi-body and continuum based models; fractals; other methods suitable for modeling particle synthesis, assembling and interaction processes. Realization and application of systems, structures and devices with novel functions obtained via precursor nanoparticles is emphasized. Approaches may include gas-, liquid-, solid-, and vacuum-based processes, size reduction, chemical- and bio-self assembly. Contributions include utilization of nanoparticle systems for enhancing a phenomenon or process and particle assembling into hierarchical structures, as well as formulation and the administration of drugs. Synergistic approaches originating from different disciplines and technologies, and interaction between the research providers and users in this field, are encouraged.
