Phonon localization
WebNov 8, 2024 · Phonon scattering and exciton localization are crucial to understand the modulation of exciton flux in two dimensional disorder energy landscape, which still remain elusive. Here, we report an optimized scheme for exciton diffusion and relaxation dominated by phonon scattering and disorder potentials in WSe 2 monolayers. WebJan 15, 2024 · Phonon Anderson localization has been receiving increasing interest in creating unique thermal transport properties. However, due to challenges to resolve and track the mode-specific transmission, the existence of phonon Anderson localization has only been inferred from the decay of overall thermal conductivity versus device length.
