摘要：

We developed a technique to form conductive LaTiO3/SrTiO3 interdiffusion layers with a sheet carrier density in the 10(13)cm(-2) to 10(15) cm(-2) range. An LaTiO3/SrTiO3 heterostructure, which showed a field effect, was used as the conductive channel of a superconducting weak link. We also demonstrated that the heterostructure's field effect can be used to control its own electronic conduction characteristics, such as the mobility depth profile.
