Unconventional room-temperature negative magnetoresistance effect in Au/n-Ge:Sb/Au devices 下载免费PDF全文
Non-magnetic semiconductor materials and their devices have attracted wide attention since they are usually prone to exhibit large positive magnetoresistance(MR) effect in a low static magnetic field environment at room temperature.However, how to obtain a large room-temperature negative MR effect in them remains to be studied. In this paper, by designing an Au/n-Ge:Sb/Au device with metal electrodes located on identical side, we observe an obvious room-temperature negative MR effect in a specif... 相似文献
