Optical Absorption and Piezoelectric Effect Investigation in Single Crystal of AgGaGe3Se7.6Te0.4 Solid Solution
Journal Title: Фізика і хімія твердого тіла - Year 2016, Vol 17, Issue 4
Abstract
In present work spectral distribution of absorption coefficient in the range of 100 – 300 K was investigated and band gap values evaluated. Parameters of Urbach rule were calculated and linearity of temperature dependence of Urbach energy was showed. Thermo induced piezoelectric effect in a range of 297 - 357 K was investigated. Laser induced kinetics of piezomodule was investigated and absence of irreversible changes was showed. Influence of heating the crystal during laser illuminating on piezoelectric module was adjusted.
