Anisotropic hot carrier relaxation mediated by electron phonon scattering in TiN thin films
Hemant Verma, Tzu-Yu Peng, Shyr-Shyan Yeh +5
The study investigates how the crystallographic orientation of TiN thin films influences electron‑phonon mediated hot‑carrier relaxation, combining first‑principles calculations wi…

Electrically Controllable Flat Band in Two-Dimensional Electron Gases under Nonuniform Magnetic Fields
You-Ting Huang, Chao-Cheng Kaun, Ching-Hao Chang
Flat bands underlie a diverse range of quantum phenomena, from strongly correlated phases to superconductivity. We theoretically establish that a two-dimensional electron gas under…

Driving noncollinear interlayer exchange coupling intrinsically in magnetic trilayers
Guan-Wei Peng, Hung-Chin Wang, Yu-Jie Zhong +2
Ferromagnetic side layers sandwiching a nonmagnetic spacer as a metallic trilayer has become a pivotal platform for achieving spintronic devices. Recent experiments demonstrate tha…
