Figure 4From: Doping dependence of low-energy quasiparticle excitations in superconducting Bi2212Dispersion kinks manifested in NQP spectra. The ARPES spectra were taken in the superconducting state for Bi2212[7]. (a) Underdoped sample with Tc = 66 K (UD66). (b) Optimally doped sample with Tc = 91 K (OP91). (c) Overdoped sample with Tc = 80 K (OD80).Back to article page
