通过对SrTiO3环形元件热处理前后三电极间电压的比较,利用晶界势垒模型和导电模型,讨论了正反电压差异的起因,并由此分析了热处理时晶界处电荷分布的变化及其对势垒高度的影响。结果是通过热处理可以使势垒高度变大,电压上升,三电极电压均匀性得到改善。
By comparing the voltage between the three electrodes before and after heat treatment of SrTiO3 ring element, the origin of the difference between the positive and negative voltage is discussed by using the barrier model and the conduction model. And the change of the charge distribution at the grain boundary during heat treatment and its effect on The impact of barrier height. As a result, the barrier height can be increased by heat treatment and the voltage can be increased, and the voltage uniformity of the three electrodes can be improved.
