采用表面活性剂辅助溶胶-凝胶法合成介孔钛酸钡（BT）薄膜。由于介孔诱导的有效应变，所获得的介孔BT薄膜表现出增强的铁电性。介孔BT的居里温度（T-c）达到约470摄氏度。
Mesoporous barium titanate (BT) thin films are synthesized by a surfactant-assisted sol-gel method. The obtained mesoporous BT thin films show enhanced ferroelectricity due to the effective strains induced by mesopores. The Curie temperature (T-c) of the mesoporous BT reaches approximately 470 degrees C.
