论文摘要
我们使用角度分辨的光发射来绘制srmoo $ _3 $的散装薄膜的费米表面和准粒子分散体,该薄膜是由脉冲激光沉积生长的。从我们的数据中得出的电子能源表明,SRMOO $ _3 $中的弱至中度相关性,这与我们在整个占用的频段宽度上观察到定义明确的电子状态。我们进一步介绍了光谱函数计算,将动态平均场理论与密度功能计算的展开过程相结合,并在我们的实验中证明了这种方法的良好一致性。
We use angle-resolved photoemission to map the Fermi surface and quasiparticle dispersion of bulk-like thin films of SrMoO$_3$ grown by pulsed laser deposition. The electronic self-energy deduced from our data reveals weak to moderate correlations in SrMoO$_3$, consistent with our observation of well-defined electronic states over the entire occupied band width. We further introduce spectral function calculations that combine dynamical mean-field theory with an unfolding procedure of density functional calculations and demonstrate good agreement of this approach with our experiments.
