Alternative Materials for Thin, Flexible LEDs

An article in Photonics Online has explained research published in Nanoscale Horizons on work by researchers at the Ultrafast Laser Lab at the University of Kansas to use ‘atomically thin’ layers of molybdenum disulfide and rhenium disulfide to potentially create LEDs that can be very efficient and also flexible. The group has used the same concepts of creating thin layers using scotch tape to create very thin devices that has been used to create graphene.

The group is using its ultrafast lasers to confirm the theoretical calculations performed by Li and Zeng. These predicted the properties of around a dozen atomic sheets and that bilayers formed by MoS2 and ReS2 would have potential in an LED application.

As graphene developers have found, moving from a small scale lab experiment to industrial production of these ‘2D’ materials is very tricky. (BR)
