Valence band-anticrossing in GaP1−xBix dilute bismide alloys: giant bowing of the band gap and spin-orbit splitting energy
<p>Using spectroscopic ellipsometry measurements on GaP1−xBix/GaP epitaxial layers up to x = 3.7% we observe a giant bowing of the direct band gap (EgΓ) and valence band spin-orbit splitting energy (∆SO). EgΓ (∆SO) is measured to decrease (increase) by approximately 200 meV (240 meV) with the incorporation of 1% Bi, corresponding to a greater than fourfold increase in ∆SO in going from GaP to GaP0.99Bi0.01. The evolution of EgΓ and ∆SO with x is characterised by strong, composition-dependent bowing. We demonstrate that a simple valence band-anticrossing model, parametrised directly from atomistic supercell calculations, quantitatively describes the measured evolution of EgΓ and ∆SO with x. In contrast to the well-studied GaAs1−xBix alloy, in GaP1−xBix substitutional Bi creates localised impurity states lying energetically within the GaP host matrix band gap. This leads to the emergence of an optically active band of Bi-hybridised states, accounting for the overall large bowing of EgΓ and ∆SO and in particular for the giant bowing observed for x <= 1%. Our analysis provides insight into the action of Bi as an isovalent impurity, and constitutes the first detailed experimental and theoretical analysis of the GaP1−xBix alloy band structure.</p> <p> </p> <p> </p>
Ge1-xSnx alloys: Consequences of band mixing effects for the evolution of the band gap Γ-character with Sn concentration
<p>In this work we study the nature of the band gap in GeSn alloys for use in silicon-based lasers. Special attention is paid to Sn-induced band mixing effects. We demonstrate from both experiment and ab-initio theory that the (direct) Γ-character of the GeSn band gap changes continuously with alloy composition and has significant Γ-character even at low (6%) Sn concentrations. The evolution of the Γ-character is due to Sn-induced conduction band mixing effects, in contrast to the sharp indirect-to-direct band gap transition obtained in conventional alloys such as Al<sub>1-x</sub>Ga<sub>x</sub>As. Understanding the band mixing effects is critical not only from a fundamental and basic properties viewpointbut also for designing photonic devices with enhanced capabilities utilizing GeSn and related material systems.</p>
