Tunable Conductivity and Conduction Mechanism in a UV light activated electronic conductor
M. I. Bertoni, T. O. Mason, J. E. Medvedeva +3
A tunable conductivity has been achieved by controllable substitution of a novel UV light activated electronic conductor. The transparent conducting oxide system H-doped Ca12-xMgxA…
First-principles characterization of ferromagnetic Mn5Ge3 for spintronic applications
S. Picozzi, A. Continenza, A. J. Freeman
In the active search for potentially promising candidates for spintronic applications, we focus on the intermetallic ferromagnetic Mn5Ge3 compound and perform accurate first-princi…
Hopping versus bulk conductivity in transparent oxides: 12CaO.7Al2O3
J. E. Medvedeva, A. J. Freeman
First-principles calculations of the mayenite-based oxide, [Ca12Al14O32]{2+}(2e-), reveal the mechanism responsible for its high conductivity. A detailed comparison of the electron…
Electronic structure and light-induced conductivity in a transparent refractory oxide
J. E. Medvedeva, A. J. Freeman, M. I. Bertoni +1
Combined first-principles and experimental investigations reveal the underlying mechanism responsible for a drastic change of the conductivity (by 10 orders of magnitude) following…
