Enhancement in the optoelectronic and thermoelectric properties of the NaASb (A= Ca, Sr and Ba) Sodium Antimonides via switching from P4/ nmm to P62 m symmetry

In the present work, investigation is carried out on these compounds on how the change in structure symmetry influences the opto-electronic and thermoelectric properties and enhances as going from P4/nmm to P62 m symmetry with addition of replacing Ca by Sr and Ba.
