Growth optimization of InGaAs quantum wires for infrared photodetector applications

Abstract

Influence of rapid thermal annealing on a 30 stack InAs/GaAs quantum dot infrared photodetector J. Appl. Phys. 94, 5283 (2003); 10.1063/1.1609634Effect of Be doping on the absorption of InGaAs/AlGaAs strained quantum-well infrared photodetectors grown by molecular-beam epitaxyWe studied the quantum wire photodetector ͑QRIP͒ structures with an InGaAs quantum wires ͑QWRs͒ active region formed by the strain-induced lateral ordering ͑SILO͒ process. The InGaAs multiple layer QWR structure maintains a small total strain due to the strain-balanced nature of the SILO process. The effects of growth temperature and layer structures on the QWR formation are studied using photoluminescence and transmission electron microscope measurements. High-resolution x-ray diffraction studies on QRIP structures consisting of 20 QWR layers confirmed the strain-balanced property of SILO-based structures.

Tailoring detection wavelength of InGaAs quantum wire infrared photodetector

“…11 The active region consists of three QWR layers with six, eight, or ten pairs of ͑GaAs͒ m / ͑InAs͒ n SPSs in each layer, where m and n are the number of monolayers for GaAs and InAs, respectively. The growth optimization process of SILO-based QWRs has been discussed elsewhere.…”

Generation-recombination processes in InGaAs/GaAs heterostructures with one-dimensional nanostructures

“…IPs based on quantum wires (QWRs) have been less thoroughly investigated [25][26][27] both theoretically and experimentally. The QWR intersubband IPs (QWRIPs), as well as QD intersubband IPs (QDIPs), allow for absorption of normal incident light 13,25 and have discrete energy spectra allowing for flexibility in wavelength engineering of the infrared spectrum.…”
