Spectroscopic ellipsometry has been used to measure the dielectric function ε (ω) of InP
from 30 to 750 K in the 1.3–5.5-eV photon-energy region. By performing a line-shape …

The last decade of semiconductor research has been characterized by a very strong
interaction with the development of optoelectronic devices, and there are no signs of …

Modulation spectroscopy is an optical characterization tool that can be of great utility to the
materials scientist. We present here numerous examples where a simple photo-reflectance …

A study is made of the oscillatory spectral distribution of the photovoltaic (PV) effect of a gold-
indium phosphide Schottky barrier in magnetic fields of up to 70 kG. Spectra are obtained for …

Non-fullerene acceptor molecules developed for organic solar cells feature a very intense
absorption band in the near-infrared. In the solid phase, the strong interaction between light …

The isotropic analytical exchange interaction Δ a of GaAs and InP is determined to be
0.02±0.01 and 0.04±0.015 meV, respectively, for the two materials from a comparison of …

A method is developed to obtain Wannier-Mott—exciton wave functions in semiinfinite
crystals in the framework of the effective-mass approximation. An analytical approximation is …

Corrections to the exciton energies due to exchange interaction and polar electron-phonon
coupling are considered for the degenerate-band case. Mass renormalization and electron …

The field of polariton-mediated light scattering is obviously a very rich one. It first gives a
direct visualisation of those fundamental hcoupled-mode excitations, the excitonic …

Four sharp lines in very pure InP vapor-phase epitaxial layers are identified by absorption
and luminescence experiments to be due to excitons bound to a shallow neutral donor in the …
