effect of the extrinsic and temporal carriers on radiative recombination of iii-nitride nanostructures

due to many important applications, the group iii-nitride semiconductors have recently attractedremarkable attention among semiconductor researchers and engineers. in this paper, we report on the impact of extrinsic and temporal carriers on the screening of polarization internal fields. the optical efficiency of gan/algan multiple quantum well (mqw) nanostructures were studied by means of photo...

Radiative transfer effects in hydrogen recombination masers

Using a simple on-the-spot approximation, we explore the parameter range in the (log(R), log(ne)) plane for which maser action in atomic hydrogen is present and briefly discuss how the borderlines of this region of strong population inversion arise. In particular we address the influence of radiative transfer on the population structure. We find that in normal HII regions no strong maser activi...

Radiative Transfer Effects in He I Emission Lines

We consider the effect of optical depth of the 2 S level on the nebular recombination spectrum of He I for a spherically symmetric nebula with no systematic velocity gradients. These calculations, using many improvements in atomic data, can be used in place of the earlier calculations of Robbins. We give representative Case B line fluxes for UV, optical, and IR emission lines over a range of ph...

Spectroscopic Observation Radiative Recombination of Ground State Oxygen Atoms

Detailed knowledge of the continuous radiation processes contributing to the emission and absorp­ tion of low tem perature plasmas, as encountered in e.g. laboratory electrical discharges, high pres­ sure discharge lamps and shock-tube plasmas is still missing in m any cases. This is the reason why active research is continuing in such a classic field of plasma spectroscopy [1, 2, 3, 4]. In a r...

Multiphoton Radiative Recombination of Electron Assisted by Laser Field

In the presence of an intensive laser field the radiative recombination of the continuum electron into an atomic bound state generally is accompanied by absorption or emission of several laser quanta. The spectrum of emitted photons represents an equidistant pattern with the spacing equal to the laser frequency. The distribution of intensities in this spectrum is studied employing the Keldysh-t...
