利用非相互作用的紧束缚模型研究了孤立氢吸附物对单层石墨烯准粒子谱的影响。利用绿色函数方法，我们得到了氢掺杂石墨烯的局域态密度和光谱函数的解析表达式，并进行了数值计算和绘制。我们的研究结果是相关的扫描隧道显微镜和角度分辨光电子能谱数据的功能化石墨烯的解释。
We use the non-interacting tight-binding model to study the effect of isolated hydrogen adsorbates on the quasiparticle spectra of single-layer graphene. Using the Green's function approach, we obtain analytic expressions for the local density of states and the spectral function of hydrogen-doped graphene, which are also numerically evaluated and plotted. Our results are relevant for the interpretation of scanning tunneling microscopy and angle-resolved photoemission spectroscopy data of functionalized graphene.
