摘要: The doping evolution of the nodal electron dynamics in the trilayer cuprate superconductor $\mathrm{Bi_{2}Sr_{2}Ca_{2}Cu_{3}O_{10+\delta}}$ (Bi2223) is investigated using high-resolution laser-based angle-resolved photoemission spectroscopy (ARPES). Bi2223 single crystals with different doping levels are prepared by controlled annealing, which cover the underdoped, optimally-doped and overdoped regions. The electronic phase diagram of Bi2223 is established which describes the $T_{\rm c}$ dependence on the sample doping level. The doping dependence of the nodal Fermi momentum for the outer (OP) and inner (IP) CuO$_2$ planes is determined. Charge distribution imbalance between the OP and IP CuO$_2$ planes is quantified, showing enhanced disparity with increasing doping. Nodal band dispersions demonstrate a prominent kink at $\sim94$ meV in the IP band, attributed to the unique Cu coordination in the IP plane, while a weaker $\sim60$ meV kink is observed in the OP band. The nodal Fermi velocity of both OP and IP bands is nearly constant at $\sim1.62$ eV$\cdot$Å independent of doping. These results provide important information to understand the origin of high $T_{\rm c}$ and superconductivity mechanism in high temperature cuprate superconductors.
