Query: Doping Controlled Superconductor-Insulator Transition in
  Bi2Sr2-xLaxCaCu2O8+delta   We show that the doping-controlled superconductor-insulator transition (SIT)
in a high critical temperature cuprate system (Bi2Sr2-xLaxCaCu2O8+delta)
exhibits a fundamentally different behavior than is expected from conventional
SIT. At the critical doping, the sheet resistance seems to diverge in the zero
temperature limit. Above the critical doping, the transport is universally
scaled by a two-component conductance model. Below, it continuously evolves
from weakly to strongly insulating behavior. The two-component conductance
model suggests that a collective electronic phase separation mechanism may be
responsible for this unconventional SIT behavior.
