Electron glass effects in amorphous NbSi films
J. Delahaye, T. Grenet, C. A Marrache-Kikuchi +3
We report on non equilibrium field effect in insulating amorphous NbSi thin films having different Nb contents and thicknesses. The hallmark of an electron glass, namely the logari…
Evidence for thermal activation in the glassy dynamics of insulating granular aluminum conductance
T. Grenet, J Delahaye
Insulating granular aluminum is one of the proto-typical disordered insulators whose low temperature electrical conductance exhibits ubiquitous non-equilibrium phenomena. These inc…
Charging of highly resistive granular metal films
M. F. Orihuela, M. Ortuno, A. M. Somoza +4
We have used the Scanning Kelvin probe microscopy technique to monitor the charging process of highly resistive granular thin films. The sample is connected to two leads and is sep…
The question of intrinsic origin of the metal-insulator transition in i-AlPdRe quasicrystal
Julien Delahaye, Claire Berger
The icosahedral (i-) AlPdRe is the most resistive quasicrystalline alloy discovered so far. Resistivities () of at 4K and correlated resistance ratios ($RRR = ρ_{4K}/ρ_{3…
Full Field Supercritical Angle Fluorescence Microscopy for live cell imaging
Thomas Barroca, Karla Balaa, Julie Delahaye +2
We introduce a full field fluorescence imaging technique with axial confinement of about 100 nm at the sample/substrate interface. Contrary to standard surface imaging techniques,…
Screening and conductance relaxations in insulating granular aluminium thin films
Julien Delahaye, Thierry Grenet
We have recently found in insulating granular Al thin film a new experimental feature (Delahaye et al., Phys. Rev. Lett. 106, 186602, 2011), namely the existence of a conductance r…
