Room‐Temperature Mid‐Infrared Detection Using Metasurface‐Absorber‐Integrated Phononic Crystal Oscillator

Laser &Photonics Reviews, EarlyView.
Room‐temperature mid‐infrared (MIR) detectors are demonstrated using lithium niobate surface acoustic wave phononic crystal oscillators integrated with metasurface absorbers. The devices exhibit rapid thermal response and simplified fabrication compared to suspended resonators.

Metal‐Insulator‐Semiconductor Structure‐Based InGaN/GaN Micro‐Light‐Emitting Devices with Superior External Quantum Efficiency

Laser &Photonics Reviews, EarlyView.
Micro‐LEDs with a novel metal‐insulator‐semiconductor (MIS) sidewall structure enable bias control of surface recombination and efficiency. Applying a positive sidewall voltage improves more than 50% EQE at low current density and achieves a record‐high 53.9% EQE.

Experimental Study on Polymer–Polymer Interfacial Thermal Resistance

Macromolecular Theory and Simulations, Volume 34, Issue 2, March 2025.
Interfacial thermal resistance (ITR) in polymer–polymer interfaces is experimentally measured in this paper by the multi‐layered bulk sample approach. Based on numerical simulation and experimental verification, new techniques of layer‐overlapping samples are developed.

Sputter Epitaxy of Transition Metal Nitrides: Advances in Superconductors, Semiconductors, and Ferroelectrics

physica status solidi (a), EarlyView.
In this review, sputter epitaxy is highlighted as a key technique for growing transition metal nitrides such as NbN and ScAlN. By integrating these materials with nitride semiconductors, hybrid devices showing both superconducting and ferroelectric properties can be realized.

ScAlN/GaN High Electron Mobility Transistor Heterostructures Grown by Ammonia Source Molecular Beam Epitaxy on Silicon Substrate

physica status solidi (a), EarlyView.
In this work, ammonia source molecular beam epitaxy is explored as an alternative technique to grow ScAlN/GaN high electron mobility transistor heterostructures on a silicon substrate. A transistor with a maximum drain current superior to 1 A mm−1 has been fabricated on a 23 nm thick ScAlN barrier.
