AbstractThe fabrication and characterization of GaN MQW microdisks pivoted on Si is reported in this paper. The GaN microdisks were patterned by photolithography and dry-etched. This is followed by an isotropic wetetch process to remove the Si underneath the GaN microdisks, exposing the bottom GaN surface. A Si pillar is left behind to support the microdisk structure. The smooth GaN/air interface provides a reflectivity of ∼20%. Modal features are observed in the photoluminescence spectrum with a mode spacing of ∼ 1.1 nm. From theoretical predictions whispering gallery (WG) modes are likely to dominate in these microdisks structures. © 2007 WILEY-VCH Verlag GmbH & Co. KGaA.
