Recently, high-quality crystals of lightly-doped Bi2212 have become available $^{9}$, which enabled us to study the systematic doping dependence covering from the insulator to the superconductor. In particular, substituting La for the Sr site instead of substituting for the Ca site has made lightly-doped Bi2212 samples metallic ( dρ/dT > 0) in an anal- ogous way to the lightly-doped LSCO 10 and YBa$_{2}$Cu$_{3}$O$_{7}$$_{−}$$_{δ}$(YBCO) $^{11}$. Single crystals of Bi$_{2}$Sr$_{2}$$_{−}$$_{x}$La$_{x}$CaCu$_{2}$O$_{8+}$$_{δ}$ and Bi$_{2}$Sr$_{2}$Ca$_{0}$$_{.}$$_{8}$Y$_{0}$$_{.}$$_{2}$Cu$_{2}$O$_{8+}$$_{δ}$ were grown by the traveling solvent floating-zone method. X-ray diffraction showed no trace of impurity phases. Details of the sample preparation are given elsewhere $^{9}$. The hole concentration p per Cu atom was deter- mined using the empirical relationship between p and the room-temperature thermopower $^{12}$. All the samples show metallic transport at 300 K, while some of them show insulating be- havior ( dρ/dT < 0) at low temperatures. p , T$_{c}$ , T$_{min}$ and ρ$_{min}$ of the measured samples are listed in Table. I. Here, T$_{min}$ is the temperature at which the resistivity reaches the minimum value ρ$_{min}$ . The Bi$_{2}$Sr$_{2}$Ca$_{0}$$_{.}$$_{8}$Y$_{0}$$_{.}$$_{2}$Cu$_{2}$O$_{8+}$$_{δ}$ ( p =0 . 075) sample was superconducting and above T$_{c}$ dρ/dT > 0. ARPES measurements were carried out at beamline 5-4 of Stanford Synchrotron Radia- tion Laboratory (SSRL). Incident photons had an energy of h ν =19 eV. A SCIENTA SES-200 analyzer was used in the angle mode with the total energy and momentum resolution of ∼ 14 meV and ∼ 0 . 3 ◦ , respectively. Samples were cleaved in situ under an ultrahigh vacuum of 10 $_{−}$11 Torr, and measured at ∼ 10 K. The position of the Fermi level was calibrated with gold spectra. Figure 1(a)-(d) shows energy distribution curves (EDCs) along the diagonal k =(0 , 0)- ( π, π ) direction (nodal direction) in the second Brillouin zone (BZ). The intensity maps in E - k space shown in Figs 1(e)-(h) reveal the peak dispersion. First, the spectra for p =0 . 03 show a single dispersive peak marked by “ MB (main band)” plus a diffraction replica marked by “ SS ” due to the Bi-O plane superstructure. This peak disperses closest to E$_{F}$ around ∼ ( π/ 2 , π/ 2), and can be considered as a remnant of the LHB or more precisely of the Zhang- Rice singlet band. With hole doping p , the dispersive peak as a whole moves upward until III. RESULTS AND DISCUSSION II. EXPERIMENTS 3
