We show that a Meyer-Neldel (MN) regime, usually reported for disordered materials, is found in state-of-the-art monocrystalline Si MOSFETs. This unexpected result is explained via device simulation in terms of the self-consistency between the mobile charge and the device electrostatics. The dependence on device parameters is then discussed, showing that neglecting this effect can lead to interpretation errors for data evaluated at low activation energies.

Abstract
We show that a Meyer-Neldel (MN) regime, usually reported for disordered materials, is found in state-of-the-art monocrystalline Si MOSFETs. This unexpected result is explained via device simulation in terms of the self-consistency between the mobile charge and the device electrostatics. The dependence on device parameters is then discussed, showing that neglecting this effect can lead to interpretation errors for data evaluated at low activation energies.File in questo prodotto:
