On the detectivity of quantum-dot infrared photodetectors
We report on the analysis of thermally-limited operation of quantum-dot infrared photodetectors ~QDIPs!. A device model is developed and used to calculate the QDIP detectivity as a function of the structural parameters, temperature, and applied voltage, as well as to determine the conditions for the detectivity maximum. The QDIP detectivity is compared with that of quantum-well infrared photode...
متن کاملQuantum grid infrared photodetectors
In this letter we introduce a quantum well infrared photodetector ~QWIP! structure, which we refer to as the quantum grid infrared photodetector ~QGIP!. In an ideal structure, a grid pattern with very narrow linewidth is created in the QWIP active region to achieve lateral electron confinement, thereby improving its absorption as well as transport characteristics. In order to realize this detec...
متن کاملNormal-Incidence InAs Self-Assembled Quantum-Dot Infrared Photodetectors With a High Detectivity
An InAs/AlGaAs quantum-dot infrared photodetector based on bound-to-bound intraband transitions in undoped InAs quantum dots is reported. AlGaAs blocking layers were employed to achieve low dark current. The photoresponse peaked at 6.2 m. At 77 K and 0.7 V bias, the responsivity was 14 mA/W and the detectivtiy, , was 10 cm Hz /W. M IDand far-infrared (3–20 m) detection is a key technology for n...
متن کاملOptimization of blazed quantum-grid infrared photodetectors
In a quantum-grid infrared photodetector ~QGIP!, the active multiple quantum well material is patterned into a grid structure. The purposes of the grid are, on the one hand, to create additional lateral electron confinement and, on the other, to convert part of the incident light into parallel propagation. With these two unique functions, a QGIP allows intersubband transition to occur in all di...
متن کاملUnclassified, distribution unlimited MULTICOLOR QUANTUM WELL INFRARED PHOTODETECTORS
Multicolor infrared (IR) detectors are very important to advanced IR sensor systems. An IR detector with multicolor capability can offer a better target discrimination, tracking, and identification, as well as temperature determination. Multicolor IR sensors are also very useful in industry for gas leakage detection, chemical analysis, and for environmental sensing and control. As the IR techno...
