Abstract

A method of fabricating a multicolor light-emitting diode (LED) display includes forming a first LED layer on a first release layer comprising a first two-dimensional (2D) material disposed on a first substrate. The first LED layer is configured to emit light at a first wavelength. The method also includes transferring the first LED layer from the first release layer to a host substrate and forming a second LED layer on a second release layer comprising a second 2D material disposed on a second substrate. The second LED layer is configured to emit light at a second wavelength. The method also includes removing the second LED layer from the second release layer and disposing the second LED layer on the first LED layer.
