Atomically thin semiconductors known as transition metal dichalcogenides (TMDCs) could lead to devices that operate more efficiently than conventional semiconductors in light-emitting diodes, lasers, and solar cells. Now scientists have discovered that when they applied an electrical voltage to TMDCs made of molybdenum disulfide and tungsten disulfide, their efficiency increases significantly.
