Normal incidence detection of ultraviolet, visible, and mid-infrared radiation in a single GaAs/AlGaAs device.
نویسندگان
چکیده
A GaAs/AlGaAs detector is demonstrated showing multiple detection capabilities. This detector exhibits a broad spectral response in the 200-870 nm (ultraviolet-visible) range for forward bias and in the 590-870 nm (visible) range for reverse bias. In the mid-IR region, two peaks at 5 and 8.9 microm can be observed for low and high forward bias voltages, respectively. In addition, the peak at 8.9 microm is sensitive to the polarization of the incoming radiation.

InAs quantum dot infrared photodetectors with In0.15Ga0.85As strain-relief cap layers
As a potential candidate for mid-infrared ~3–5 mm! and far-infrared ~8–14 mm! photon detection, the quantum dot infrared photodetector ~QDIP! has been the subject of extensive research efforts in recent years. Normal-incidence QDIPs with n-n-n and n-i-n vertical configurations have been reported. Compared with quantum well infrared photodetectors, QDIPs are sensitive to normal-incidence infrare...

We report on the results of our simulations of Γ−X scattering in GaAs/AlGaAs heterostructures, discussing the importance of the mole fraction, doping density, and lattice and electron temperature in determining the scattering rates. We consider three systems, a single quantum well (for the investigation of Γ−X scattering), a double quantum well (to compare the Γ−X−G and Γ−Γ scattering rates), a...
متن کاملLight Spectrum of Compact Fluorescent Lamps in Iranian Market and Possibility of Hydroxyl Radical Production
Background and purpose: Despite growing use of energy-saving lamps or compact fluorescent lamps (CFLs), there are concerns about ultraviolet radiation in their output. In this study, the output of CFLs available in Iranian market in the range of infrared, visible, and ultraviolet were measured and the possibility of hydroxyl radical production by their radiation was evaluated. Materials and me...
متن کاملAsymmetrically Shaped Pseudomorphic Modulation Doped Structure for Microwave Detection
In this paper we propose a microwave detector based on a AlGaAs/ InGaAs/GaAs structure. Its operation relies on non-uniform carrier heating of the two-dimensional electron gas in the microwave electric fields which is a result of the asymmetric shape of the device fabricated on the base of pseudomorphic modulation doped AlGaAs/InGaAs/GaAs structure. The voltage sensitivity of the device at nitr...
متن کاملQWIP and MCT for Long Wavelength and Multicolor Focal Plane Array Applications
Infrared (IR) sensor technology is critical to all phases of ballistic missile defense. Traditionally, material systems such as indium antimonide (InSb), platinum silicide (PtSi), mercury cadmium telluride (MCT), and arsenic doped silicon (Si: As) have dominated IR detection. Improvement in surveillance sensors and interceptor seekers requires large, highly uniform, and multicolor (or multispec...
