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 ...

Design Optimization of a New Nanostructured P-GaN Gate for Normally-off GaN HEMTs [PDF]

open access: yes, 2022
Best Paper AwardInternational audienceA new AlGaN/GaN heterostructure is proposed to achieve a normally-off behavior for GaN HEMTs. It relies on multiple P-GaN wells epitaxial regrowth along the gate.

XHEMTs on Ultrawide Bandgap Single‐Crystal AlN Substrates

open access: yesAdvanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.
AlN/GaN/AlN XHEMTs [single‐crystal (“X‐tal”) high‐electron‐mobility transistors] are built on bulk AlN substrates with a 20 nm pseudomorphic GaN channel. This coherent epitaxial double heterostructure promises low‐defect, thermally efficient nitride electronics for next‐generation RF technology.

Influence of polarization coulomb field scattering on the subthreshold swing in E-mode p-GaN/AlGaN/GaN HEMTs

open access: yesJournal of Physics Communications
In the present study, p-GaN/AlGaN/GaN HEMTs treated with hydrogen plasma passivation were fabricated. Capacitance–voltage (C-V) and current–voltage(I-V) characteristics of these devices were subsequently measured.

Normally-off p-GaN Gated AlGaN/GaN HEMTs Using Plasma Oxidation Technique in Access Region

open access: yesIEEE Journal of the Electron Devices Society, 2020
Normally-off p-GaN gated AlGaN/GaN high electron mobility transistors (HEMTs) were developed. Oxygen plasma treatment converted a low-resistive p-GaN layer in the access region to a high-resistive GaN (HR-GaN); that oxygen plasma treatment used an AlN ...

Electronic Transport in AlGaN/GaN Nanowires Under Ultraviolet Excitation and Edge Depletion Effect, Studied in a Wide Temperature Range

open access: yesNano Select, Volume 7, Issue 2, February 2026.
Electronic transport in AlGaN/GaN nanowires (NW) was studied under ultraviolet excitation in a wide temperature range. Significant changes in the conductivity of the structures were revealed and explained by the modulation of the space charge limited current (SCLC) effect. Temperature‐dependent measurements of transport and noise properties using noise

Gate Characteristics of Enhancement-Mode Fully Depleted p-GaN Gate HEMT [PDF]

open access: yes, 2023
The conventional p -GaN in Schottky-type p -GaN gate HEMTs is converted into an insulator-like p -GaN, i.e., fully depleted p -GaN in the reverse-biased Schottky junction under forward gate bias ( VGS ), by inadequate activation of Mg.
