A study on photoacoustic spectrum of ZnTe and ZnSe crystal
Description
The sound generated from a periodically illuminated solid as a photoacoustic effects first discovered in 1881 is used to investigate the properties of materials. The PA spectra of ZnTe and ZnSe crystal were obtained by PAS method. The absorption spectrum of materials which is not accesible with optical spectroscopy can be obtained by PA spectroscopy. The PA signals were proportional to absorption coefficient and the energy bandgaps of ZnTe and ZnSe crystal were measured as 2.01 eV and 2.55 eV respectively. The characteristics of energy transition of ZnTe and ZnSe crystals were investigated as the direct allowed transition by PA spectroscopy. (Author)
