Abstract
An Al0.5Ga0.5As/GaAs quantum wires infrared photo-detectors (QWRIP) based on V-grooved substrate is fabricated. The inter-hand transition in the quantum wires is characterized by spatially resolved micro-photoluminescence (micro-PL) measurement. The theoretical calculation of electronic structures is accomplished based on the Green function. The inter-subband transition is measured by photocurrent at 80 K, and the origin of the infrared response at 9 μm is from the inter-subband transition in quantum wire region, which is confirmed by the theoretical calculation results.
