论文摘要
我们对抗拉力和压缩菌株的石墨烯和硅氧烯对工作函数的系统{\ it i a in hibio}进行了系统的研究及其均匀的应变依赖性。还计算了与扶手椅和锯齿形菌株相关的泊松比。基于这些结果，我们获得了变形电位，对于应变菌株的函数而言，对于应变菌株至关重要。此外，我们提出了一种具有特殊应变构型的特定实验设置，该设置仅生成电场，而假磁场则不存在。然后，应用一个真实的磁场，应该能够在实验上实现石墨烯或相关二维材料中兰道水平崩溃的壮观现象。
We perform a systematic {\it ab initio} study of the work function and its uniform strain dependence for graphene and silicene for both tensile and compressive strains. The Poisson ratios associated with armchair and zigzag strains are also computed. Based on these results, we obtain the deformation potential, crucial for straintronics, as a function of the applied strain. Further, we propose a particular experimental setup with a special strain configuration that generates only the electric field, while the pseudomagnetic field is absent. Then, applying a real magnetic field, one should be able to realize experimentally the spectacular phenomenon of the collapse of Landau levels in graphene or related two-dimensional materials.
