However, transition metal oxides hosting flat bands are quite rare. In this study, we investigate the origin of the existing nearly flat bands (NFBs) in SrRuO$_3$ thin films and demonstrate how to increase the number of them through structural modifications. Using a tight-binding model that replicates experimental band structures, we analyze the SrRuO$_3$ monolayer, revealing the origin of its NFBs along the $x$ and $y$ directions.
