GazeQwen: Lightweight Gaze-Conditioned LLM Modulation for Streaming Video Understanding
Trong Thang Pham, Hien Nguyen, Ngan Le
Current multimodal large language models (MLLMs) cannot effectively utilize eye-gaze information for video understanding, even when gaze cues are supplied via visual overlays or te…
Atomic Alignment in PbS Nanocrystal Superlattices with Compact Inorganic Ligands via Reversible Oriented Attachment of Nanocrystals
Ahhyun Jeong, Aditya N. Singh, Josh Portner +12
Nanocrystals (NCs) serve as versatile building blocks for the creation of functional materials, with NC self-assembly offering opportunities to enable novel material properties. He…
Ultrafast symmetry control in photoexcited quantum dots
Burak Guzelturk, Joshua Portner, Justin Ondry +23
Symmetry control is essential for realizing unconventional properties, such as ferroelectricity, nonlinear optical responses, and complex topological order, thus it holds promise f…
Colloidal dispersions of sterically and electrostatically stabilized PbS quantum dots: the effect of stabilization mechanism on structure factors, second virial coefficients, and film-forming properties
Ahhyun Jeong, Josh Portner, Christian P. N. Tanner +7
Electrostatically stabilized nanocrystals (NCs) and, in particular, quantum dots (QDs) hold promise for forming strongly coupled superlattices due to their compact and electronical…
Advanced Techniques in Automated High Resolution Scanning Transmission Electron Microscopy
Alexander Pattison, Cassio C. S. Pedroso, Bruce E. Cohen +4
Scanning transmission electron microscopy is a common tool used to study the atomic structure of materials. It is an inherently multimodal tool allowing for the simultaneous acquis…
A composite electrodynamic mechanism to reconcile spatiotemporally resolved exciton transport in quantum dot superlattices
Rongfeng Yuan, Trevor D. Roberts, Rafaela M. Brinn +9
Quantum dot (QD) solids are promising optoelectronic materials; further advancing their device functionality depends on understanding their energy transport mechanisms. The commonl…
Examining the Role of Chloride Ligands on Defect Removal in Imperfectly Attached Semiconductor Nanocrystals for 1D and 2D Attachment Cases
Amy S. McKeown-Green, Justin C. Ondry, Michelle F. Crook +2
Semiconducting, core-shell nanocrystals (NCs) are promising building blocks for the construction of higher dimensional artificial nanostructures using oriented attachment. However,…
Characterization of Carrier Cooling Bottleneck in Silicon Nanoparticles by Extreme Ultraviolet (XUV) Transient Absorption Spectroscopy
Ilana J. Porter, Angela Lee, Scott K. Cushing +4
Silicon nanoparticles have the promise to surpass the theoretical efficiency limit of single-junction silicon photovoltaics by the creation of a "phonon bottleneck", a theorized sl…
Photoexcited Small Polaron Formation in Goethite (α-FeOOH) Nanorods Probed by Transient Extreme Ultraviolet Spectroscopy
Ilana J. Porter, Scott K. Cushing, Lucas M. Carneiro +6
Small polaron formation limits the mobility and lifetimes of photoexcited carriers in metal oxides. As the ligand field strength increases, the carrier mobility decreases, but the…
