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…
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…
Femtosecond two-pulse laser approach for spall failure in thin foils
Mewael Isiet, Yunhuan Xiao, Jerry I. Dadap +2
Spall failure in materials occurs when tensile waves, propagating through a material, interact leading to failure once the generated hydrostatic stress exceeds the material's stren…
Observation of oscillatory relaxation in the Sn-terminated surface of epitaxial rock-salt SnSe topological crystalline insulator
Wencan Jin, Suresh Vishwanath, Jianpeng Liu +20
Topological crystalline insulators have been recently predicted and observed in rock-salt structure SnSe thin films. Previous studies have suggested that the Se-terminate…
