Mott transition field effect transistor: a nanodevice?

A field effect transistor device (FET), consisting of a nonlinear Mott Insulator channel material, and a high dielectric-constant gate oxide, is explored as a nanoscale device. Experimental functionality of a large scale prototype (5 μm channel length) has been demonstrated. The underlying physics of the device is analyzed and modeled using a time-dependent Hartree approach. Timing estimates suggest a relatively short switching time.
