The future of movies and manufacturing may be in 3D, but electronics and photonics are going 2D semiconducting materials. One of the latest advancements centers on molybdenum disulfide (MoS2), while commonly used in lubricants and steel alloys, is still being explored inoptoelectronics. Recently, engineers placed a single layer of MoS2 molecules on top of a photonic structure called an optical nanocavity made of aluminum oxide and aluminum. (A nanocavity is an arrangement of mirrors that allows beams of light to circulate in closed paths which build things like lasers and optical fibers used for communications.)
The MoS2 nanocavity can increase ...
