Prediction of Novel Stable 2D-Silicon with Fivefold Coordination

Autor: Wang, Zhenhai, Zhao, Mingwen, Zhou, Xiang-Feng, Zhu, Qiang, Zhang, Xiaoming, Dong, Huafeng, Oganov, Artem R., He, Shumin, Grünberg, Peter

Silicene, an analogue of graphene, was so far predicted to be the only two-dimensional silicon (2D-Si) with massless Dirac fermions. Here we predict a brand new 2D-Si Dirac semimetal, which we name siliconeet [silik'ni:t]. Unexpectedly, it has a much

Large rectification magnetoresistance in nonmagnetic Al/Ge/Al heterojunctions

Autor: Zhang, Kun, Li, Huan-huan, Grünberg, Peter, Li, Qiang, Ye, Sheng-tao, Tian, Yu-feng, Yan, Shi-shen, Lin, Zhao-jun, Kang, Shi-shou, Chen, Yan-xue, Liu, Guo-lei, Mei, Liang-mo

Magnetoresistance and rectification are two fundamental physical properties of heterojunctions and respectively have wide applications in spintronics devices. Being different from the well known various magnetoresistance effects, here we report a bra
