Electron–hole doping asymmetry of Fermi surface reconstructed in a simple Mott insulator

It is widely recognized that the effect of doping into a Mott insulator is complicated and unpredictable, as can be seen by examining the Hall coefficient in high Tc cuprates. The doping effect, including the electron-hole doping asymmetry, may be more straightforward in doped organic Mott insulators owing to their simple electronic structures. Here we investigate the doping asymmetry of an org...

Electronics with Correlated Oxides: SrVO(3)/SrTiO(3) as a Mott Transistor.

We employ density functional theory plus dynamical mean field theory and identify the physical origin of why two layers of SrVO(3) on a SrTiO(3) substrate are insulating: the thin film geometry lifts the orbital degeneracy, which in turn triggers a first-order Mott-Hubbard transition. Two layers of SrVO(3) are just at the verge of a Mott-Hubbard transition and hence ideally suited for technolog...

A Field Effect Transistor based on the Mott Transition in a Molecular Layer

Here we propose and analyze the behavior of a FET–like switching device, the Mott transition field effect transistor, operating on a novel principle, the Mott metal–insulator transition. The device has FET-like characteristics with a low “ON” impedance and high “OFF” impedance. Function of the device is feasible down to nanoscale dimensions. Implementation with a class of organic charge transfe...

Switching a normal insulator into a topological insulator via electric field with application to phosphorene.

The study of topological insulators has generally involved search of materials that have this property as an innate quality, distinct from normal insulators. Here we focus on the possibility of converting a normal insulator into a topological one by application of an external electric field that shifts different bands by different energies and induces a specific band inversion, which leads to a...
