Summary

Descripción general del contenido del recurso.

<p>The modulation spectroscopy was used for defining band gap of monocrystalline Cd<sub>1-x</sub>Mn<sub>x</sub>Te solid solutions, the properties of which vary with molar composition <em>x</em> and the surface preparation quality. It was found that for such samples it is useful to measure differential transmission spectrum , the main peak of which is governed by the composition <em>x</em> and the substrate thickness <em>d</em>. Therefore, it is important to measure <em>E<sub>g</sub></em>(<em>d</em>) for at least three samples of the same composition and different thickness. Using these data, the band gap can be obtained by extrapolating <em>E<sub>g</sub></em>(<em>d</em>) dependence in a logarithmic scale up to intersection with the energy axis at lg <em>d</em> = 0, which corresponds to the sample thickness of 1 μm.</p> <p> </p> <p><strong>Keywords</strong>: semiconductor, band gap, modulation spectroscopy.</p>
