Title: Multiple-hydrogen complexes in dilute nitride alloys

Abstract

Complexes formed by H and the isoelectronic impurity N in GaAs1-yNy alloys have been widely investigated to explain the significant effects of N on the host material properties and their passivation by H. However, available results still present a quite puzzling picture, none of the models proposed by theory for the N-H complexes being able to account for all of the experimental findings. An N-H{sub 2}* complex first proposed by theory was challenged by infrared results. A following C2{nu} complex has been challenged by a recent high resolution x-ray diffraction and photoluminescence spectroscopy study questioning the structural effects of this complex. In the present study, we show that a peculiar character of the H interaction with an isoelectronic impurity can induce the formation of novel, multiple-H complexes. In turn, one of this complexes can account for the H structural effects recently observed, thus reconciling theory and experiment.

  • By means of high resolution x-ray diffraction and photoluminescence measurements we demonstrate that, as a result of hydrogen irradiation of GaAs1-xNx/GaAs, the original tensile strain of the as-grown material is reversed into a compressive one and that, at the same time, N atoms are electronically passivated. We show that the amount of compressive strain is determined exclusively by N concentration. This compressive strain is caused by the formation of peculiar N-H complexes and disappears after moderate annealing, while N electronic passivation still holds. These experimental results demonstrate that the lattice properties of fully-hydrogenated GaAs1-xNx/GaAs are ruled by a H complexmore » which is different and less stable than that responsible for electronic passivation of N in GaAs1-xNx/GaAs.« less
  • Dilute nickel alloys charged with hydrogen are known to exhibit an internal friction peak, which is attributed to the reorientation of hydrogen-solute atom pairs. In order to determine the geometrical configuration of the pair, the authors have studied anisotropy of the relaxation strength in dilute Ni-Ti-H alloy single crystals by low-frequency internal friction measurements. The orientation dependence of the peak height suggests that the defect symmetry is {l_angle}111{r_angle} trigonal. One of the possible configurations is the Ti-H pair in which hydrogen occupies the second neighbor octahedral sites around the substitutional solute atom. The peak has been found to be suppressedmore » by an external magnetic field, indicating that magneto-elastic effects play an important role.« less
  • We report the growth of InAsN onto GaAs substrates using nitrogen plasma source molecular beam epitaxy. We describe the spectral properties of InAsN alloys with N-content in the range of 0%-1% and photoluminescence emission in the midinfrared spectral range. The photoluminescence emission of the sample containing 1% N reveals localized energy levels resonant with the conduction band states of InAsN.
  • The addition of dilute concentrations of bismuth (Bi) into GaAs to form GaBi{sub x}As{sub 1−x} alloys results in a large reduction of the band gap energy (E{sub g}) accompanied by a significant increase of the spin-orbit-splitting energy (Δ{sub SO}), leading to an E{sub g} < Δ{sub SO} regime for x ∼ 10% which is technologically relevant for the design of highly efficient photonic devices. The quaternary alloy GaBi{sub x}N{sub y}As{sub 1−x−y} offers further flexibility for band gap tuning, because both nitrogen and bismuth can independently induce band gap reduction. This work reports sp{sup 3}s* tight binding and 14-band k⋅p modelsmore » for the study of the electronic structure of GaBi{sub x}As{sub 1−x} and GaBi{sub x}N{sub y}As{sub 1−x−y} alloys. Our results are in good agreement with the available experimental data.« less
  • Ultrasonic attenuation and velocity measurements were performed to probe the structure and annealing behavior of self-interstitial solute complexes in electron-irradiated (T<70 K) dilute Al-Ag and Al-Si alloys. In both alloy systems, a similar attenuation peak structure is observed. Three peaks are observed to anneal in unison during stage II, suggesting that they arise from the presence of a single defect structure. The annealing of this defect structure follows a first-order rate equation which has a prefactor proportional to the solute concentration. The diaelastic effect associated with this defect is found to be comparable in magnitude and anisotropy to that attributedmore » to <100> self-interstitial dumbbells in pure aluminum. A <110> monoclinic mixed dumbbell model which can account for much of the observed behavior of this defect structure is proposed.« less
