论文摘要
在密度功能理论的框架内，使用自旋极化计算进行了扭曲的石墨烯纳米纤维的几何，电子和磁性。考虑了在中点和垂直于纳米替比平面的纳米替比和拉伸应力的较长轴的压缩应力病例。观察到显着的结构变化，包括纳米质的形成。计算出的电子和磁性在很大程度上取决于纳米容器的大小和形状。应变的纳米管的可调磁性能可用于设计磁性纳米转换。
The geometric, electronic and magnetic properties of strained graphene nanoribbons were investigated using spin polarized calculations within the framework of density functional theory. Cases of compressive stress along the longer axis of a nanoribbon and tensile stress at the midpoint and perpendicular to the plane of the nanoribbon were considered. Significant structural changes were observed including the formation of nanoripples. The calculated electronic and magnetic properties strongly depend on the size and shape of nanoribbons. The tunable magnetic properties of strained nanoribbons can be employed for designing magnetic nano-switches.
