    Notes:
    Long wavelength infrared detection using intersubband transitions has been progressing rapidly in recent years. One advantage of the quantum-well infrared photodetectors is the wavelength tunability as a function of their structural parameters. In this work, we have performed a systematic calculation on the detection wavelength, the absorption linewidth, and the oscillator strength of a typical GaAs/AlxGa1−xAs multiple-quantum-well photodetector, with aluminum molar ratio in the barriers ranging from 0.14 to 0.42 and the quantum-well width ranging from 20 to 70 A(ring). We found that within these material parameters, the detection wavelength can be varied from 5 to over 25 μm. In addition, we also discuss the photoconductive gain of the detectors with respect to the energies of the final state of the optical transition and the satellite valleys of the detector material.

    Notes:
    GaAs/AlGaAs quantum wells are grown on gas source molecular-beam epitaxy (GSMBE) grown low-temperature buffers (LTB). Changes in LTB growth conditions produce noticeable changes in photoluminescence (PL) intensity and linewidths of the quantum wells. Layers grown at low temperatures (200–300 °C) incorporate excess arsenic which outdiffuses during subsequent quantum well growth. Reflection high energy electron diffraction and PL results are utilized to show strain and arsenic outdiffusion from the LTBs. Excess arsenic incorporation during the growth of GaAs at low temperatures is explained in 〈m1;&10q〉terms of the association reaction of As2 to form As4 at the surface. The optimum V/〈bx〉III〈ba〉 ratio for growth of LTB by GSMBE is discussed.

    Notes:
    The emission from KCl@B:Sb3+ and KI@B:Sb3+ excited in the A-absorption band was measured as a function of exciting photon energy and temperature. The A-band excitation produced two emission bands for KCl@B:Sb3+ and a single band for KI@B:Sb3+. The definitive assignment of these bands is presented in terms of the adiabatic potential energy surface (APES), in which the effect of the spin–orbit interaction (SO) on the Jahn–Teller (JT) interaction coupling to the Eg mode is taken into account. The polarization spectrum and the angular dependence of polarization ratio of the A-band emission were also studied to determine the symmetry axes of the Sb3+ –vacancies complex. The results indicate that the anisotropy is associated with the relaxed excited state (RES) of Sb3+. It is also found that the JT interaction coupling to the T2g mode and the vacancies, situated in the next-nearest-neighbor (nnn) and the nearest-neighbor (nn) positions to the Sb3+ ion, give rise to an additive perturbation.

    Notes:
    Photoluminescence (PL) in PbWO4 single crystals doped with Pr3+, Sm3+, and Er3+ ion, which were grown by the Czochralski method, was studied. By investigating the PL for incident radiation with wavelength of 325 nm (He–Cd Laser), the energy levels of the PL centers were found: The PL levels in the Pr doped single crystal are 3Po and 1D2, that in the Sm-doped one is 4G5/2, and those in the Er doped one are 2H11/2, 4S3/2, and 4F9/2. In conclusion, the characteristics of these single crystals are governed solely by those of the rare-earth dopants, not by the lead tungstate. © 2002 American Institute of Physics.

    Notes:
    In this article, we discuss the utilities of corrugated quantum well infrared photodetectors (C-QWIPs) in detector material characterization. By measuring the detector responsivity as a function of corrugation period, several important detector parameters, such as the absorption coefficient α of parallel propagating light and the energy resolved photoconductive gain g, can be directly deduced. For the QWIP material presented, α at the peak was found to be 0.21 μm−1 under the usual operating condition. This value of α corresponds to an absorption length of 4.8 μm. Instead of being a constant, the value of g also varies significantly across the excitation spectrum, and the peak value is larger than the noise gain at large bias. Our results show that the present characterization technique is capable of providing accurate and detailed information on the intrinsic properties of QWIP materials under actual operating conditions. It is extremely useful in detector optimization. In addition, we also show the characteristics of C-QWIPs with an additional vertical trench at the center of each corrugation to gain more insights into the distribution of light intensity in a C-QWIP structure. © 2000 American Institute of Physics.
