  In metal/oxide/metal capacitor-like structures,the interface between the switching material and the electrode can play an important role in resistive switching.When depositing oxide thin films on a metal bottom electrode at elevated temperatures,the interdiffusion at the oxide/metal interface becomes an essential factor.This influences the metal/oxide contact formation and the electrical properties of the whole capacitor stack.This work reports the effect of Ti diffusion on the bipolar resistive switching in Au/BiFeO3/Pt/Ti capacitor-like stuctures.Polycrystalline BiFeO3 thin films are deposited by pulsed laser deposition at different temperatures on Pt/Ti/SiO2/Si substrates.

摘要:数学源于生活,用于生活。在小学数学教学中,如果能够根据小学生的认知特点,将数学知识与学生的生活实际紧密结合,那么,在他们的眼里,数学将是一门看得见、摸得着、用得上的学科,不再是枯燥乏味的数字游戏。这样,学生学起来自然感到亲切、真实,这也有利于培养学生用数学的眼光观察周围事物的兴趣、态度和意识。对于学生更好地认识数学、学好数学、培养能力、发展智力、促进综合素质的发展,具有重要的意义。  关键词
