4H-SiC microring resonators for nonlinear integrated photonics.

Optics Letters, 2019
We demonstrate enhanced four-wave mixing (FWM) in high-quality factor, high-confinement 4H-SiC microring resonators via continuous-wave FWM. With the large power buildup effect of the microring resonator, -21.7  dBFWM conversion efficiency is achieved ...

Deep Learning Atmospheric Models Reliably Simulate Out‐of‐Sample Land Heat and Cold Wave Frequencies

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Deep learning (DL)–based general circulation models (GCMs) are emerging as fast simulators, yet their ability to replicate extreme events outside their training range remains unknown. Here, we evaluate two such models—the hybrid Neural General Circulation Model (NGCM) and purely data‐driven Deep Learning Earth System Model (DLESyM)—against a ...

Threshold displacement energies and displacement cascades in 4H-SiC: Molecular dynamic simulations

AIP Advances, 2019
Molecular dynamic (MD) simulations were used to study threshold displacement energy (TDE) surface and Si displacement cascades in 4H-SiC system. To figure out the role of different Wyckoff sites in determining the TDE values, both Si and C atoms in 2a ...

Ultrahigh Strength with Suppressed Flow Instability at Liquid Helium Temperature via Coherent Nanoprecipitation in a Medium‐Entropy Alloy

Advanced Functional Materials, Volume 36, Issue 10, 2 February 2026.
It is demonstrated that severe lattice distortion and coherent nanoprecipitates overcome the strength–ductility dilemma and mitigate discontinuous plastic flow (DPF) at 4.2 K. Such microstructural design enhances both thermal and athermal stress components, leading to exceptional mechanical performance.

Effect of Gate Length Relative to Recess Coverage on the Performance of Enhancement‐Mode β‐Ga2O3 MOSFETs

Advanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.
Gate‐length engineering in recessed‐gate enhancement‐mode β‐Ga2O3 metal‐oxide‐semiconductor filed effect transistors was investigated by extending the gate to fully cover the etched recess. Complete recess coverage improves electrostatic control, reduces series resistance, shifts the threshold voltage positively, and enhances mobility, on‐resistance ...
