摘要:

使用Floquet理论结合照明石墨烯和石墨烯纳米带的电子结构的现实描述的开发,以评估出现的非绝热和非微扰效应的电子性质。在这里,我们介绍了一个有效的计算方案,并说明其使用通过将其应用到石墨烯纳米带中存在的线性和圆偏振。由于有限的样品尺寸和激光诱导的过渡之间的相互作用的限制,导致尖锐的平均电导和状态密度的功能。特别强调的是批量限制响应的出现。

英文摘要:

The use of Floquet theory combined with a realistic description of the electronic structure of illuminated graphene and graphene nanoribbons is developed to assess the emergence of non-adiabatic and non-perturbative effects on the electronic properties. Here, we introduce an efficient computational scheme and illustrate its use by applying it to graphene nanoribbons in the presence of both linear and circular polarization. The interplay between confinement due to the finite sample size and laser-induced transitions is shown to lead to sharp features on the average conductance and density of states. Particular emphasis is given to the emergence of the bulk limit response.
