The effect of doping crystals of tgs with some di- and trivalent ions on its: (i) dielectric constant and a.c. Conductivity
Gaffar, M. A [محمد عبد العزيز جعفر]; Al-Houty, L. I.; Al-Muraikhi, M. ( Qatar University , 1987 , Article)The problem of the existence of a new ferroelectric phase transition at low temperatures in TGS crystals is discussed. The influence of some inorganic divalent and trivalent ions presented in the lattice of TGS on dielectric ... -
The effect of doping crystals of tgs with some di- and trivalent ions on its: (ii) polarization and piezoelectricity
