Fabrication of AlGaN/GaN Fin-Type HEMT Using a Novel T-Gate Process for Improved Radio-Frequency Performance

IEEE Access, 2020
To increase the radio-frequency (RF) performance of AlGaN/GaN-based fin-type high electron mobility transistors (HEMTs), a novel T-gate process was developed and applied to fabricate a device with high RF performance. In a single lithography process, the

Automated Plasmon‐Selective Laser Writing in Mesoporous Thin Films Through Decoupling of the Initiator Absorption and Plasmon Wavelength

Small Science, Volume 6, Issue 3, March 2026.
Plasmon‐selective direct laser writing is demonstrated in mesoporous silica thin films containing plasmonic Au nanospheres. The key to attain plasmon‐selective polymerization is decoupling the plasmon wavelength from the absorption profile of coreactants, hence suppressing mutual radiative interactions.

Label‐Free Sensing of Coronaviral Sequences via Kretschmann‐Configuration Reflectance Spectroscopic Ellipsometry: Sensitivity, Specificity, and Interfacial Effects

Advanced Materials Interfaces, Volume 13, Issue 4, 17 February 2026.
Spectroscopic ellipsometry in the Kretschmann‐Raether configuration (KRSE) is employed to characterize a DNA‐functionalized platform for viral sequence recognition. By merging SE with surface plasmon resonance, KRSE outperforms conventional SE, achieving nanomolar targeting through resonance wavelength shifts (δλ) measurements. Its enhanced interfacial

Magnetic Direct-Write Skyrmion Nanolithography

ACS Nano, 2020
Magnetic skyrmions are stable spin textures with quasi-particle behavior and attract significant interest in fundamental and applied physics. The metastability of magnetic skyrmions at zero magnetic field is particularly important to enable, for instance, a skyrmion racetrack memory. Here, the results of the nucleation of stable skyrmions and formation
