Monolithic Integration of ScAlN Modulators on Silicon‐On‐Insulator Platform

Laser &Photonics Reviews, EarlyView.
Monolithic integration of scandium‐doped aluminum nitride (ScAlN) modulators on a silicon‐on‐insulator platform is reported. A multilayer electrode design enhances RF‐optical field overlap, enabling direct access to the diagonal electro‐optic coefficient and improved modulation efficiency.

Vacancy‐Type Defects in n‐Type GaN Fabricated by Low‐Dose Ion Implantation Studied by a Monoenergetic Positron Beam

physica status solidi (b), EarlyView.
Vacancies in low‐dose ion‐implanted GaN are studied by positron annihilation. Depth profiles of the net donor concentration (ND) are close to those for implanted impurities, but ND is 2–3 times higher than concentrations of implanted ions. The origin of donor‐like defects is expected to be N‐vacancy‐related defects, and Ga‐vacancy‐type defects play a ...

Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their
