Abstract

Transmission dark‐field spectra (DFS), i.e. the transmittivity of a sample positioned between crossed linear polarizers, are measured on differently spontaneously ordered GaInP layers in the energy range from 1.65 to 1.90 eV. Using a generalized light polarization transfer 4 × 4‐matrix technique the ordering induced band‐gap reduction and the valence band splitting are deduced from the DF spectra. Due to the dark‐field technique the results do not depend on the volume fraction, the size, and the shape of the ordered domains inside the layers.
