A composite electrodynamic mechanism to reconcile spatiotemporally resolved exciton transport in quantum dot superlattices

Posted by dbos Berkeley

Kavli Affiliate: Paul Alivisatos | First 5 Authors: Rongfeng Yuan, Trevor D. Roberts, Rafaela M. Brinn, Alexander A. Choi, Ha H. Park | Summary: Quantum dot (QD) solids are promising optoelectronic materials; further advancing their device functionality depends on understanding their energy transport mechanisms. The commonly invoked near-field F"orster resonance energy transfer (FRET) theory often […]

Establishing Coherent Momentum-Space Electronic States in Locally Ordered Materials

Posted by klaurent Berkeley

Kavli Affiliate: Alessandra Lanzara | First 5 Authors: Samuel T. Ciocys, Quentin Marsal, Paul Corbae, Daniel Varjas, Ellis Kennedy | Summary: In our understanding of solids, the formation of highly spatially coherent electronic states, fundamental to command the quantum behavior of materials, relies on the existence of discrete translational symmetry of the crystalline lattice. In […]

Rydberg Excitons and Trions in Monolayer MoTe$_2$

Posted by klaurent Caltech

Kavli Affiliate: Harry A. Atwater | First 5 Authors: Souvik Biswas, Aurélie Champagne, Jonah B. Haber, Supavit Pokawanvit, Joeson Wong | Summary: Monolayer transition metal dichalcogenide (TMDC) semiconductors exhibit strong excitonic optical resonances which serve as a microscopic, non-invasive probe into their fundamental properties. Like the hydrogen atom, such excitons can exhibit an entire Rydberg […]

Semantic-Guided Generative Image Augmentation Method with Diffusion Models for Image Classification

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Bohan Li, Xiao Xu, Xinghao Wang, Yutai Hou, Yunlong Feng | Summary: Existing image augmentation methods consist of two categories: perturbation-based methods and generative methods. Perturbation-based methods apply pre-defined perturbations to augment an original image, but only locally vary the image, thus lacking image diversity. In contrast, […]
