On the Material Parameters of Some Useful Quaternary Compounds Relevant to Optoelectronic Device Design
Shruti Dutta Roy
Studies about some quaternary compounds showing lattice matching condition on various substrates suitable for device design in various wavelength regions are reported here. The compositional dependence of lowest energy band gap, dielectric constant, coefficient of thermal expansion, temperature and pressure dependence of lowest band gap energy, etc. of these compounds are presented and finally proper concentrations suitable for device design under lattice matching condition is given.
Keywords: Band gap, dielectric constant, electro-optical properties, quaternaries.
