Thin-film blue light-emitting diodes for flexible device operation down to a millimetric radius of curvature

Résumé

We report on the fabrication and characterization of flexible blue thin-film micro-LED grown by MOVPE. Two approaches are explored to replace laser lift-off for the micro-LED device liberation from the growth substrate: the release of the micro-LED structures assisted by quasi-van der Waals epitaxy using an interfacial h-Bn layer; and the sacrificial etching of the growth substrate starting from LED structures on Si(111). We demonstrate the transfer of micro-LED on a polyimide substrate and their operation down to a millimetric radius of curvature.
