Abstract
An organic light-emitting diode with an inorganic two-dimensional (2D) EL active material may comprise a plurality of layers on a plastic or glass substrate. In addition to the EL layer, the device may comprise a hole injection layer, a hole transport layer/electron blocking layer, an electron transport layer/hole blocking layer, an electron injection layer, and optional buffer layers such as poly(methyl methacrylate) (PMMA) to help balance the charge injection into the 2D material and redistribute the electric field.
