Temperature dependence of the interband critical-point parameters of InP
Abstract
Spectroscopic ellipsometry has been used to measure the dielectric function \ensuremath{\epsilon}(\ensuremath{\omega}) of InP from 30 to 750 K in the 1.3--5.5-eV photon-energy region. By performing a line-shape analysis of the structures observed, the temperature dependence of the interband critical-point parameters (strength, threshold energy, broadening, and excitonic phase angle) has been determined. The decrease in energy and the increase in broadening with increasing temperature are analyzed in terms of averaged frequencies of phonons giving rise to the renormalization of the band states due to electron-phonon interaction.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
