MIT researchers have developed a new material that is two-dimensional to create devices that have the ability to harness or emit light. The material, called tungsten diselenide (WSe2), could produce ultrathin, lightweight and flexible optoelectronic devices.
The team of researchers used the material to create diodes using a sheet of WSe2 material. The working diode had ideal properties and has led the team to produce the three basic types of optoelectronic devices – photodetectors, photovoltaic cells and LEDs. These devices are only proof-of-concept, but the demonstrations of these devices could lead to a wide range of potential uses.
