We summarize previous field effect studies in high- T c cuprates and then discuss our method to smoothly tune the carrier concentration of a cuprate film over a wide range using an applied electric field. We synthesized epitaxial one-unit-cell thick films of La 2− x Sr x CuO 4 and from them fabricat...
