Isolating Exciton Dissociation Pathways in ReSe
Bradley G. Guislain, Rysa Greenwood, Matteo Michiardi +13
Strongly bound excitons dominate the optical response in many van der Waals semiconductors, yet distinguishing between the different microscopic processes governing exciton dissoci…
Quenching of excitons at grain boundaries in C60 thin films
Rysa Greenwood, Bradley G. Guislain, MengXing Na +12
Exciton lifetimes play a critical role in the performance of organic optoelectronic devices. In this work, we investigate how the presence of multiple rotational domains, and there…
Enhanced coherence and layer-selective charge order in a trilayer cuprate superconductor
S. Smit, M. Bluschke, P. Moen +25
Trilayer cuprates hold the record for the highest superconducting critical temperatures (), yet the underlying mechanism remains elusive. Using time- and angle-resolv…
Correlated insulating states in slow Dirac fermions on a honeycomb moir{é} superlattice
Dongyang Yang, Jing Liang, Haodong Hu +8
Strong Coulomb repulsion is predicted to open a many-body charge gap at the Dirac point of graphene, transforming the semimetal into a Mott insulator. However, this correlated insu…
Nanosecond Ferroelectric Switching of Intralayer Excitons in Bilayer 3R-MoS2 through Coulomb Engineering
Jing Liang, Yuan Xie, Dongyang Yang +6
High-speed, non-volatile tunability is critical for advancing reconfigurable photonic devices used in neuromorphic information processing, sensing, and communication. Despite signi…
Spall failure of alumina at high-strain rates using femtosecond laser experiments and high-fidelity molecular dynamics simulations
Mewael Isiet, Musanna Galib, Yunhuan Xiao +3
Ceramic materials are widely used in high-strain-rate applications due to their exceptional strength-to-weight ratio. However, under these extreme conditions, spall failure becomes…
