quantum-well infrared photo-detector withthe near-infrared photo-detection
2007
A novel GaInNAs AlAsAIGaAs double-barrier quantum-well-infrared-photo-detector wascharacterized by photoluminescence, x-raydiffraction, photoluminescence excitation, photocurrent spectra anddarkcurrent measurements. Thephotoluminescence peakat1.2eVandthephotocurrent peakat1.24fum originate fromthe interband transition andinter-subband transition, respectively, intheGaInNAs well. Thedarkcurrent isaslowas K0-8K10-9 A.After annealing, theenergy blueshift oftheGINAphotoluminescence peakdecreases withincreasing
