From: Mid-infrared photon sensing using InGaN/GaN nanodisks via intersubband absorption
(a) Top-view SEM and (b) TEM image of the nanowire sample. (c) Photoluminance intensity of the as-grown nanowire sample measured with a continuous wave laser emitting at 266 nm, (d) intraband absorption spectra of the nanowires embedded in CYTOP measured by FTIR at room temperature with light incident normal to the sample.
