Simultaneous Observation of Carrier-Specific Redistribution and Coherent Lattice Dynamics in 2H-MoTe with Femtosecond Core-Level Spectroscopy
Andrew R. Attar, Hung-Tzu Chang, Alexander Britz +12
We employ few-femtosecond extreme ultraviolet (XUV) transient absorption spectroscopy to reveal simultaneously the intra- and interband carrier relaxation and the light-induced str…
Lattice Thermal Transport in Two-Dimensional Alloys and Fractal Heterostructures
Aravind Krishnamoorthy, Nitish Baradwaj, Aiichiro Nakano +2
Engineering thermal transport in two dimensional materials, alloys and heterostructures is critical for the design of next-generation flexible optoelectronic and energy harvesting…
Predictive Synthesis of Quantum Materials by Probabilistic Reinforcement Learning
Pankaj Rajak, Aravind Krishnamoorthy, Ankit Mishra +3
Predictive materials synthesis is the primary bottleneck in realizing new functional and quantum materials. Strategies for synthesis of promising materials are currently identified…
Growth kinetics and atomistic mechanisms of native oxidation of ZrSSe and MoS crystals
Seong Soon Jo, Akshay Singh, Liqiu Yang +14
A thorough understanding of native oxides is essential for designing semiconductor devices. Here we report a study of the rate and mechanisms of spontaneous oxidation of bulk singl…
Anisotropic structural dynamics of monolayer crystals revealed by femtosecond surface x-ray scattering
I-Cheng Tung, Aravind Krishnamoorthy, Sridhar Sadasivam +22
X-ray scattering is one of the primary tools to determine crystallographic configuration with atomic accuracy. However, the measurement of ultrafast structural dynamics in monolaye…
