论文摘要
我们通过单个屏障电势研究了对鹅的偏移（GH）偏移的应变效应，并通过单个屏障电势在裂开的石墨烯中传输的dirac费米子的群体延迟时间。能量谱的溶液用于计算传输概率以及GH偏移和组延迟时间。我们的结果表明，最后两个量的强烈取决于天气，沿扶手椅或锯齿形方向应用了应变。特别是发现，可以通过施加的应变来增强两个量。
We investigate the strain effect on the Goos-Hänchen (GH) shifts and group delay time for transmitted Dirac fermions in gapped graphene through a single barrier potential. The solutions of energy spectrum are used to compute the transmission probabilities together with the GH shifts and group delay time. Our results show that the two last quantities are strongly depending to weather the strain is applied along armchair or zigzag directions. In particular it found that both of quantities can be enhanced with the applied strain.
