Abstract
Photothermal techniques have been widely used for the determination of light absorption spectra of semiconductors, the main reason being the possibility of successfully measuring the weak absorption in the subgap region. The authors present and discuss the most relevant applications, particularly in the field of thin films of amorphous semiconductors.
