Title: Specific features of the cathodoluminescence spectra of AlInGaN QWs, caused by the influence of phase separation and internal electric fields

Abstract

The specific features of the cathodoluminescence (CL) spectra in AlInGaN heterostructures, caused by the influence of phase separation and internal electric fields, observed at varied CL excitation density, are studied. It is shown that the evolution of the CL spectrum and the variation in the spectral position of emission lines of nanoscale layers with current density in the primary electron beam makes it possible to identify the occurrence of phase separation in the layer and, in the absence of this separation, to estimate the electric-field strength in the active region of the structure.

  • Simulation of multicomponent AlInGaN-based heterostructures for their use in light-emitting diodes is performed. The effect of nonuniform distribution of In atoms in the light-emitting 'nanodiodes' on the working characteristics of the device in general are determined. A model describing the structure of multicomponent AlInGaN heterostructures for light-emitting diodes is developed.
  • We examine how internal fields affect orientational energies in superfluid /sup 3/He. We find that the orientational effect of magnetic field due to the interaction between magnetic dipole moments is increased modestly, but that the analogous effect due to the interaction between electric dipole moments induced by an external electic field is suppressed significantly. Our estimated of the electric fields required to produce orientational effects are at least an order of magnitude larger than previous ones.
  • The electronic structures of short period mGaN/nGa{sub y}Al{sub 1−y}N and mIn{sub y}Ga{sub 1-y}N/nGaN superlattices grown along the wurtzite c axis have been calculated for different alloy compositions y and various small numbers m of well- and n of barrier-monolayers. The general trends in gap behavior can, to a large extent, be related to the strength of the internal electric field, E, in the GaN and InGaN quantum wells. In the GaN/GaAlN superlattices, E reaches 4 MV/cm, while in the InGaN/GaN superlattices, values as high as E ≈ 6.5 MV/cm are found. The strong electric fields are caused by spontaneous and piezoelectric polarizations,more » the latter contribution dominating in InGaN/GaN superlattices. The influence of different arrangements of In atoms (indium clustering) on the band gap values in InGaN/GaN superlattices is examined.« less
  • Lowering the magnetic-field strength improves the conditions for sustaining a volume beam-plasma discharge and also leads to an increase in the radial current. In the process the energy consumption for separation decreases by more than order of magnitude and the separation factor grows; a value of ..cap alpha.. = 1.4 was obtained for a natural mixture of neon isotopes in this case.(AIP)
  • When external electric fields are applied to phosphors the cathodoluminescence (CL) at low beam energies is strongly affected. This experiment has been carried out on a variety of common phosphors used in cathode ray tube applications, and the electron beam energy, beam current, and electric field dependence of the CL are thoroughly characterized. It is found that the general features of these effects, particular y the strong polarity and beam energy dependence, are consistent with a model which assumes that the main effect of the electric fields is to alter the populations of electrons `and holes at the phosphor surface.more » This in turn, modulates the non-radiative energy losses that strongly affect the low-beam-energy CL efficiency. Because the external fields are applied without any direct contact to the phosphor material, the large changes seen in the CL decay rapidly as the beam-created electrons and holes polarize, shielding the externally applied bias. These results have important implications for designing phosphors which might be efficient at low electron energies.« less
