Argument Graph Uncertainty: Quantifying Uncertainty from the Logical Structure of Reasoning Chains
Simon Baur, Sumire Honda, Wojciech Samek +1
Reliable uncertainty estimation is essential for deploying large language models in high-stakes reasoning tasks, yet most existing approaches rely on expensive sampling strategies…
(Sub)nanoscale Visualization of Reconstruction-Driven Moiré Exciton Localization and Delocalization
Medha Dandu, Sriram Sankar, Giovanny Espitia +12
Spectral fingerprints in optical absorption and emission have typically been used as a signature of exciton localization in twisted moiré bilayers. However, the mechanism by which…
Topological-Insulator Heterophase Gate Stacks for Transistor Electrostatics
Minuk Song, Jiwan Kim, MD Gius Uddin +25
Conventional gate-stack scaling reduces dielectric thickness and increases permittivity while largely treating the position and electronic character of the gate-side screening boun…
Layer-Hybridized Wigner Crystals in MoSe2/WS2 Moiré Superlattice
Tianyi Ouyang, Yuze Meng, Li Yan +11
Transition metal dichalcogenide moiré heterobilayers with type-II band alignment provide a versatile platform for layer-polarized generalized Wigner crystals, in which strong Coulo…
C-band 160 Gbs-1 Zero-bias Graphene Photodetectors: Breaking the Responsivity-Bandwidth Trade-off by Heterostructure Engineering
Karuppasamy Pandian Soundarapandian, Alberto Montanaro, Ioannis Vangelidis +17
Graphene photodetectors offer ultrafast response and broadband operation, but their responsivity is typically limited by rapid hot-carrier cooling, leading to a trade-off between s…
Excitonic Mott transition without population inversion
Oleg Dogadov, Armando Genco, Allison R. Cadore +12
Exciton dissociation via the excitonic Mott transition (EMT) governs the high-density optical response of semiconductors and sets fundamental limits for optoelectronic devices. The…
Robust valley-polarized excitonic Mott states and doublons enabled by stacking-controlled moiré geometry
Hao-Tien Chu, Shou-Chien Chiu, Meng-Che Yeh +12
Atomically-thin moiré superlattices offer an optically accessible platform for interacting bosons, where strong onsite repulsion suppresses double occupancy and supports e…
Robust Interlayer Exciton Interplay in Twisted van der Waals Heterotrilayer on a Broadband Bragg Reflector up to Room Temperature
Bhabani Sankar Sahoo, Shachi Machchhar, Avijit Barua +6
We report robust room temperature interlayer excitons in transition metal dichalcogenide heterostructures engineered via precise stacking orientation and twist-angle control. We in…
Optical properties of Fermi polarons in a GaInP/MoSe2 monolayer heterostructure
Hangyong Shan, Max Waldherr, Diksha Diksha +15
Engineering optical properties, such as luminescence purity and charge transfer, is crucial for harnessing the application potential of atomically thin transition metal dichalcogen…
