Statistical thermodynamical and kinetically-limited models are applied to study the origin and evolution of space charges and band-bending effects at low-angle [001] tilt grain boundaries in YBa2Cu3O7 and the effects of Ca doping upon them. Atomistic simulations, using shell models of interatomic fo...
