… We demonstrate here a new formulation and method for measuring the energy band gap
in thick films from the reflectance data. … We have established one of the simplest methods
of determining the energy band gap 3, 4, 5, 6. In this communication we have given a
method and formulation of the technique used for finding energy band gap of thick films in
which only the reflection spectra of the film from the film side is used. …
Spectroscopic techniques are very useful for characterising semiconducting materials. We demonstrate here a new formulation and method for measuring the energy band gap in thick films from the reflectance data.
