چکیده

We calculate the |Conduction, Heavy Hole (HH)〉 |Split-off Hole (SO), HH〉 (CHSH) Auger Recombination rates for GaAs(1−x)Bix alloys, which are candidates for highly efficient telecommunication devices. A ten-band, tight-binding method, including spin-orbit coupling, was performed on a 9x9x9 strained supercell in order to generate an accurate band structure to perform the calculation on. This band structure was then unfolded to give a true E-k relation. As predicted by experiment, there should be a decrease in the Auger recombination rate as the concentration of Bismuth increases ending in a suppression at greater than ∼11% Bismuth.

Auger Recombination in GaAs from First Principles

Auger recombination is a significant loss mechanism in many optoelectronic devices. We use first-principles methods based on density functional theory to study the relative importance of direct and indirect phonon-assisted Auger recombination in GaAs and related alloys. Energy and momentum of the recombining electron−hole pair can be transferred to an Auger electron (eeh process) or an Auger ho...

SWEENEY, STEPHEN (University of Surrey) Auger and optical loss suppression in near- and mid-IR emitters based upon Bismide alloys

III-Bismides are a relatively underexplored set of III-V alloys yet offer the possibility to engineer many aspects of the band structure and band alignment which are of significant potential benefit to photonic devices. For example, the incorporation of Bismuth into binary compounds such as GaAs leads to a band anti-crossing effect. However, unlike the dilute nitrides, this occurs in the valenc...

Accurate first-principles detailed-balance determination of auger recombination and impact ionization rates in semiconductors.

The technologically important prediction of Auger recombination lifetimes in semiconductors is addressed by means of a fully first-principles formalism, based on precise energy bands and wave functions provided by the full-potential linearized augmented plane wave code. The minority carrier Auger lifetime is determined by two related approaches: (i) a direct evaluation within Fermi's golden rul...

Auger recombination suppression and band alignment in GaAsBi/GaAs heterostructures

Using a combination of experimental and theoretical techniques we present the dependence of the bandgap Eg and the spin orbit splitting energy so, with Bi concentration in GaAsBi/GaAs samples. We find that the concentration at which so,> Eg occurs at 9%. Both spectroscopic as well as first device results indicate a type I alignment.
