Fabrication of Polycrystalline La1−xMnO3+ (x = 0, 0.15) Thin Films on Si Substrates by Chemical Solution Deposition (CSD)
Polycrystalline La1−xMnO3+ (x = 0, 0.15) thin films are fabricated successfully on single crystal Si (h00) substrates using chemical solution deposition method (CSD), LaMnO3+ films with (h00) orientation and La0.85MnO3+ films with random orientation. The results show that temperature can obviously affect the orientation and crystallization of LaMnO3+ films. Moreover, it is found there exist an insulator-metal transition in the LaMnO3+ films, which can be attributed to the oxygen excess. La-deficient can improve crystallization quality and the microstructure of the film. For the La0.85MnO3+ films, show an obvious low field magnetoresistance (LFMR), which is beneficial to practice application.
