应变调控柔性电子器件磁电性质的研究进展

Effect of strain on the magnetoelectric property of flexible electronics devices

柔性电子器件具有独特的形状可塑性,因而引起了人们极大的研究热情.柔性电子器件在未来或将成为下一代电子器件的重要分支,在电子显示、二极管、生物医疗器件、太阳能电池等领域有着广阔的发展前景.近些年,许多研究人员将柔性技术与自旋电子学相结合,开始探索应变对于生长在柔性衬底上的磁电异质结磁电性质的影响,通过改变柔性衬底的曲率等手段调控器件的磁电效应.相关基础研究为磁存储器、磁传感器、非易失性阻变存储器等电子器件的研究开辟了新思路.

Flexible electronic devices have attracted great interest owing to the advantages of flexible substrates as well as its arbitrary surface geometries,which may be one key branch of next-generation electronic devices,including paper-like electronic displays,light-emitting diodes,biointegrated medical devices,and solar cells. In recent years,some researchers have combined flexible techniques with spintronics to explore the effect of strain on magnetoelectric heterojunctions grown on flexible substrates and to control the magnetic and electric properties by changing the curvature of the substrate. These studies pave the path for the designing electronic devices,including magnetic storage devices,magnetic sensors,and non-volatile resistance memory.
