You Don’t Have to Be Perfect for TMDCs to Shine Bright

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.
