On the ?-Particle Irradiation Effects in MESFETs

open access: yesphysica status solidi (a), 2000
α-particle irradiation investigations have been carried out on various structure GaAs metal-semiconductor field-effect transistors. The device characteristics were measured before irradiation and after α-particle irradiation with fluences ranging from 5×1010 to 3×1012 cm-2.

Toward 4R Electronics: Liquid‐Metal‐Enabled Thin Film, and Field‐Effect Transistors for Sustainability and E‐Waste Reduction

open access: yesAdvanced Materials Technologies, Volume 11, Issue 7, 6 April 2026.
The 4R principle—Resilience, Repairability, Recyclability, and Renewability—enables sustainable liquid‐metal transistors. LM materials provide stretchable, damage‐tolerant architectures, allow rapid circuit repair, permit full material recovery through dissolution, and support renewable fabrication cycles, forming a closed‐loop pathway toward ...

Analytical Solution to the Gradual Channel Approximation for Metal–Oxide‐Semiconductor Field‐Effect Transistors

open access: yesphysica status solidi (b), Volume 263, Issue 4, April 2026.
Schematic of a metal‐oxide‐semiconductor field‐effect transistor at pinch‐off together with the channel potential. We revisit the problem of the potential distribution in an inversion channel field effect transistor (metal–oxide‐semiconductor field‐effect transistor) within the gradual channel approximation.
