Tunneling-percolation origin of nonuniversality: theory and experiments [PDF]

, 2005
A vast class of disordered conducting-insulating compounds close to the percolation threshold is characterized by nonuniversal values of transport critical exponent t, in disagreement with the standard theory of percolation which predicts t = 2.0 for all

Piezoresistive Memories Based on Two-Dimensional Nano-Scale Electromechanical Systems

Crystals, 2022
In this work we present piezoresistive memory-bits based on two-dimensional nano-scale electro-mechanical systems. We demonstrate it is possible to achieve different electrical responses by fine control of micro-structural asymmetries and that ...
