Electron Ptychography Images Hydrogen Atom Superlattices and 3D Inhomogeneities in Palladium Hydride Nanoparticles
Zixiao Shi, Qihao Li, Himani Mishra +3
When hydrogen atoms occupy interstitial sites in metal lattices, they form metal hydrides (MHx), whose structural and electronic properties can differ significantly from the host m…
Xenon-metal pair formation in UO2 investigated using DFT+U
Linu Malakkal, Shuxiang Zhou, Himani Mishra +4
A recent experimental study on a spent uranium dioxide (UO2) fuel sample from Belgium Reactor 3 (BR3) identified a unique pair structure formed by the noble metal phase (NMP) and f…
Ultra-fast Vacancy Migration: A Novel Approach for Synthesizing Sub-10 nm Crystalline Transition Metal Dichalcogenide Nanocrystals
Pawan Kumar, Jiazheng Chen, Andrew C. Meng +9
Two-dimensional materials, such as transition metal dichalcogenides (TMDCs), have the potential to revolutionize the field of electronics and photonics due to their unique physical…
Discovering and Understanding 2D Semiconductors with High Intrinsic Carrier Mobility at Room Temperature
Chenmu Zhang, Ruoyu Wang, Himani Mishra +1
Two-dimensional (2D) semiconductors have demonstrated great potential for next-generation electronics and optoelectronics. However, the current 2D semiconductors suffer from intrin…
Exciton-driven giant non-linear overtone signals from buckled hexagonal monolayer GaAs
Himani Mishra, Sitangshu Bhattacharya
We report here a giant 780 pm/V second harmonic and 1.410 m/V third harmonic signal from single a…
Giant exciton-phonon coupling and zero-point renormalization in hexagonal monolayer boron nitride
Himani Mishra, Sitangshu Bhattacharya
We report here a giant zero-point energy renormalization of 273 meV in the direct band-gap at and a 571 meV of blue-shifting in the position of the doubly-degenerate b…
Exciton-Phonon Coupling and Band-Gap Renormalization in Monolayer WSe
Himani Mishra, Anindya Bose, Amit Dhar +1
Using a fully ab-initio methodology, we demonstrate how the lattice vibrations couple with neutral excitons in monolayer WSe2 and contribute to the non-radiative excitonic lifetime…
