Anomalous thermal activation of the electron glass dynamics in a-InOx and granular aluminum
Thierry Grenet, Julien Delahaye
In this article, we explore the temperature dependence of the electrical glassy dynamics in insulating amorphous indium oxide (a-InOx) and granular Al films. We use non-isothermal…
Electron glass signatures up to room temperature in disordered insulators
Julien Delahaye, Thierry Grenet
This paper describes the observation of non-equilibrium field effects at room temperature in four disordered insulating systems: granular Al, discontinuous Au, amorphous NbSi and a…
Ageing in granular aluminium insulating thin films
Julien Delahaye, Thierry Grenet
We present a new set of electrical field effect measurements on granular aluminium insulating thin films. We have explored how the conductance relaxations induced by gate voltage c…
Symmetrical field effect and slow electron relaxation in granular aluminium
Thierry Grenet
Conductivity and field effect measurements in thin insulating Al granular films are reported. The occurrence of a symmetrical field effect and of very slow conductance relaxations…
Metallicity of the SrTiO3 surface induced by room temperature evaporation of alumina
J. Delahaye, T. Grenet
It is shown that a metallic state can be induced on the surface of SrTiO3 crystals by the electron beam evaporation of oxygen deficient alumina or insulating granular aluminium. No…
Determination of characteristic relaxation times and their significance in glassy disordered insulators
Thierry Grenet, Julien Delahaye
We revisit the field effect procedure used to characterise the slow dynamics of glassy Anderson insulators. It is shown that in the slowest systems the procedure fails and the "cha…
Manifestation of ageing in the low temperature conductance of disordered insulators
Thierry Grenet, Julien Delahaye
We are interested in the out of equilibrium phenomena observed in the electrical conductance of disordered insulators at low temperature, which may be signatures of the electron co…
