摘要:
高次谐波光谱学是一种极具前景的候选方法,可通过全光学手段并以前所未有的时间分辨率对凝聚态物质中的电子结构与动力学进行成像。我们研究了有限尺寸六角纳米带(如graphene和hexagonal boron nitride)在armchair和zig-zag构型下的谐波谱。系统的对称性解释了所发射谐波的存在及其强度。
英文摘要:
High-harmonic spectroscopy is a promising candidate for imaging electronic structures and dynamics in condensed matter by all-optical means and with unprecedented temporal resolution. We investigate harmonic spectra from finite, hexagonal nanoribbons, such as graphene and hexagonal boron nitride, in armchair and zig-zag configuration. The symmetry of the system explains the existence and intensity of the emitted harmonics.
