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…
Asymmetrical contact scaling and measurements in MoS2 FETs
Zhihui Cheng, Jonathan Backman, Huairuo Zhang +8
Two-dimensional (2D) materials have great potential for use in future electronics due to their atomically thin nature which withstands short channel effects and thus enables better…
Visualizing the out-of-plane electronic dispersions in an intercalated transition metal dichalcogenide
Xian P. Yang, Harrison LaBollita, Zi-Jia Cheng +17
Layered transition metal dichalcogenides have rich phase diagram and they feature two dimensionality on numerous physical properties. Co1/3NbS2 is one of the newest members of this…
Spatially-Resolved Band Gap and Dielectric Function in 2D Materials from Electron Energy Loss Spectroscopy
Abel Brokkelkamp, Jaco ter Hoeve, Isabel Postmes +6
The electronic properties of two-dimensional (2D) materials depend sensitively on the underlying atomic arrangement down to the monolayer level. Here we present a novel strategy fo…

The growth of transition metal dichalcogenide (TMDC) alloys provides an opportunity to experimentally access information elucidating how optical properties change with gradual subs…
Distinguishing two-component anomalous Hall effect from topological Hall effect
Lixuan Tai, Bingqian Dai, Jie Li +14
In transport, the topological Hall effect (THE) presents itself as non-monotonic features (or humps and dips) in the Hall signal and is widely interpreted as a sign of chiral spin…
The Joint Automated Repository for Various Integrated Simulations (JARVIS) for data-driven materials design
Kamal Choudhary, Kevin F. Garrity, Andrew C. E. Reid +25
The Joint Automated Repository for Various Integrated Simulations (JARVIS) is an integrated infrastructure to accelerate materials discovery and design using density functional the…
On-the-fly Closed-loop Autonomous Materials Discovery via Bayesian Active Learning
A. Gilad Kusne, Heshan Yu, Changming Wu +13
Active learning - the field of machine learning (ML) dedicated to optimal experiment design, has played a part in science as far back as the 18th century when Laplace used it to gu…
Strain Engineering a Charge Density Wave Phase in Transition Metal Dichalcogenide 1T-VSe
