Effect Of Lanthanum Dopant On The Properties Of Cacu3ti4o12 Thin Films Synthesized By Sol-Gel Method

The CaCu3Ti4O12 (CCTO) was discovered to possess high dielectric constants, ɛ ~ 104 at low frequencies. The undoped and La doped CCTO thin films were prepared by sol-gel method. The raw materials of Ca(CH3COO)2, Cu(C2H3O2)2.H2O, Ti[OCH(CH3)2]4, were used to produce undoped CCTO thin films, whereas L...
