摘要
用溶胶-凝胶方法在LaNiO3/Si衬底上在450℃退火条件下制备了BiCrO3.薄膜XRD研究发现BiCrO3仅有少量结晶,呈(101)择优取向.铁电性测试表明,室温下薄膜具有铁电性,剩余极化强度为0.6μc/cm2,漏电流研究表明薄膜的导电机构分为三种.
BiCrO3 has been prepared on LaNiO3/Si substrate by sol -gel process at an annealing temperature of 600℃ XRD showed that the film is nearly amorphous. The measure of ferroelectricity verified the ferroelectricity of the film, and its Pr is 0.6μc/cm^2. The measure of leakage current showed that there are three type of mechanism of conduction.
