NREL theory establishes path to high-performance 2D semiconductor devices

Using 2D metal as contact for 2D semiconductor allows Schottky barrier to be tuned, due to the weak Fermi level pinning at the junction caused by the suppression of metal-induced gap states. Schematic illustrates that 2D H-NbS2 can form a Schottky-barrier-free contact with 2D semiconductor for hole transport

Researchers at the Energy Department's National Renewable Energy Laboratory (NREL) have uncovered a way to overcome a principal obstacle in using two-dimensional (2D) semiconductors in electronic and optoelectronic devices. 2D semiconductors such as molybdenum disulfide are only a few layers thick and are considered
