摘要
基于电子具有自旋的特性,介绍了自旋场效应晶体管的基本原理和研究进展;通过研究发现自旋场效应晶体管具有良好的电导开关效应,外加磁场后则呈现出磁开关效应.
Based on the spin properties of electron, we have introduced the basic principles and progress of the spin field-effect transistor (SFET). It has been shown that the SFET exhibit excellent switching effect and magnetic switching effect when external magnetic field is applied.
