Non-intrinsic origin of the Colossal Dielectric Constants in CaCu3Ti4O12
P. Lunkenheimer, R. Fichtl, S. G. Ebbinghaus +1
The dielectric properties of CaCu3Ti4O12, a material showing colossal values of the dielectric constant, were investigated in a broad temperature and frequency range extending up t…
