Filler Dependencies of Electrical Conductivity in Nanotube and Nanofiber Composites
G. Ambrosetti, C. Grimaldi, T. Maeder +2
We report on a model of polymer nanocomposites with fibrous fillers which explicitly considers the microscopic filler features and replicates the composites as random distributions…

Strain modulation of transport criticality in heterogeneous solids
Sonia Vionnet, Claudio Grimaldi, Thomas Maeder +2
A vast class of disordered conducting-insulating compounds close to the percolation threshold is characterized by nonuniversal values of transport critical exponents. The lack of u…

Piezoresistive anisotropy of percolative granular metals
C. Grimaldi, P. Ryser, S. Straessler
The piezoresistive response of granular metals under uniaxial strain is strongly dependent on the concentration of the conducting phase. Here we show that the piezoresistive anisot…
