Two-Dimensional Transition Metal Dichalcogenides for Electronics and Optoelectronics
This community researches atomically thin semiconductors and insulators, primarily transition metal dichalcogenides, to build next-generation transistors, photodetectors, and quantum devices.
The work centers on the synthesis of monolayer molybdenum disulfide (MoS2), tungsten disulfide (WS2), and related compounds using chemical vapor deposition and atomic layer deposition. Researchers stack these layers into van der Waals heterostructures to control charge transfer and electronic structure. Key applications include field-effect transistors with sub-nanometer gate lengths, broadband photodetectors for infrared and visible light, and twisted bilayer systems exhibiting superconductivity and fractional quantum anomalous Hall effects. Boron nitride serves as a critical dielectric and substrate material in these stacks.
Molybdenum research accounts for 11.7% of all molybdenum studies, with 15,472 papers in this group. Tungsten research contributes 4.1% of its total output, and carbon research contributes 0.6%.
The community comprises 38,038 papers, published most frequently in Physical Review B, ACS Nano, and Nano Letters.
Recent work focuses on the robust epitaxy of single-crystal transition metal dichalcogenides, interface engineering for enhanced photodetector efficiency, and the development of large-area nanofilms for optoelectronic synapses.
