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…

Robust Broadband Infrared Unidirectional Absorption Enabled by a Non-Hermitian Multilayer
Ayaha Yamamoto, Ganbat Batorgil, Yu-Jung Lu +2
Unidirectional electromagnetic absorption provides a powerful approach for controlling light and heat, yet broadband realization in the infrared spectral region remains experimenta…
