The Mott metal-insulator transition, driven by electron-electron interactions, is challenging to control directly in solid-state systems, especially within the complex environments of neuromorphic devices. Here, the authors demonstrate that interface-induced screening in LaTiO₃/SrTiO₃ heterostructures can continuously tune interaction strength, enabling an isothermal Mott transition, thus offering a promising method for manipulating Mott physics through correlation control.
