Studying quantum phase transitions at oxide interfaces provide a key to understand emergent two-dimensional (2D) superconductivity. Here, Chen et al. report comprehensive electronic phase diagram of the 2D electron system at the superconducting LaAlO3/SrTiO3 interface with independent control of carrier density and disorder.
