Anisotropic hot carrier relaxation mediated by electron phonon scattering in TiN thin films
Hemant Verma, Tzu-Yu Peng, Shyr-Shyan Yeh +5
Crystal orientations can shape the ultrafast energy relaxations of transition-metal nitride thin films. Here, we investigate the orientation-dependent electron-phonon (e-ph) mediat…

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…
