Abstract

This research work addresses the critical need for advanced semiconductor devices in radio frequency (RF) applications by investigating Cylindrical Surrounding Double-Gate (CSDG) MOSFETs with La₂O₃ oxide. The work employs comprehensive modeling approaches, including Auger recombination, Band-To-Band Tunneling (BTBT), and energy transport models, analyze device performance. Key findings demonstrate a symmetric electron density distribution, peaking at the channel center with a gradual decline towards the edges, confirming superior electrostatic control. The CSDG MOSFET achieves exceptional performance metrics: subthreshold swing values of 20.0–23.5 mV/decade and an ION/IOFF ratio of 1.89 × 104, significantly outperforming conventional designs by 65% and 300% respectively. Energy-transmission analysis reveals an inverse exponential correlation T(E) = 0·85e-0·02E, with transmission coefficient decreasing from 0.8 at 10 eV to 0.05 at 200 eV. The novel La₂O₃/AlGaAs material system provides enhanced electrostatic control, reduced short-channel effects, and superior thermal management compared to SiO₂ and HfO₂ systems, making CSDG MOSFETs promising candidates for next-generation 5G/6G applications and low-power IoT devices.
