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…
Conductance distribution in two-dimensional localized systems
J. Prior, A. M. Somoza, M. Ortuno
We have obtained the universal conductance distribution of two-dimensional disordered systems in the strongly localized limit. This distribution is directly related to the Tracy-Wi…
Delocalization by Disorder in Layered Systems
Dmitrii L. Maslov, Vladimir I. Yudson, Andres M. Somoza +1
Motivated by anomalously large conductivity anisotropy in layered materials, we propose a simple model of randomly spaced potential barriers (mimicking stacking faults) with isotro…
Mean Free Path and Energy Fluctuations in Quantum Chaotic Billiards
E. Louis, E. Cuevas, J. A. Verges +1
The elastic mean free path of carriers in a recently introduced model of quantum chaotic billiards in two and three dimensions is calculated. The model incorporates surface roughne…
