no sir these are semiconductors<br> and yes you are right but how can plasma frequencies be derived for these one of the paper Phys. Status Solidi B 248, No. 3 (2011) derived them...also please guide to do optical calculations for tetragonal compounds.<br>also sir one more problem that for the 0eV the Im epsilon has a non zero value..(its bandgap 1.29) as below..would you suggest why it is so ????<br># Energy [eV] Re_eps_xx Im_eps_xx Re_eps_zz Im_eps_zz<br> 0.013610 0.725736E+01 0.738507E-01 0.736507E+01 0.775948E-01<br>
