Exciton-phonon coupling induces new pathway for ultrafast intralayer-to-interlayer exciton transition and interlayer charge transfer in WS2-MoS2 heterostructure: a first-principles study

Kavli Affiliate: Jeffrey B. Neaton | First 5 Authors: Yang-hao Chan, Mit H. Naik, Jonah B. Haber, Jeffrey B. Neaton, Steven G. Louie | Summary: Despite the weak, van-der-Waals interlayer coupling, photoinduced charge transfer vertically across atomically thin interfaces can occur within surprisingly fast, sub-50fs timescales. Early theoretical understanding of the charge transfer is based […]

On the Statistical Mechanics of Mass Accommodation at Liquid-Vapor Interfaces

Kavli Affiliate: David T. Limmer | First 5 Authors: Kritanjan Polley, Kevin R. Wilson, David T. Limmer, , | Summary: We propose a framework for describing the dynamics associated with the adsorption of small molecules to liquid-vapor interfaces, using an intermediate resolution between traditional continuum theories that are bereft of molecular detail and molecular dynamics […]

Observation of periodic optical spectra and soliton molecules in a novel passively mode-locked fiber laser

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Haobin Zheng, Kangrui Chang, Yong Shen, Yongzhuang Zhou | Summary: Due to the necessity of making a series of fine adjustments after mode-locking in most experiments for preparing soliton molecules, the repeatability of the preparations remains a challenge. Here, we propose a novel all-polarization-maintaining erbium-doped […]
