Quantum percolation in quantum spin Hall antidot systems
Quantum percolation quantum spin Hall antidot systems
2012/2/27
We study the influences of antidot-induced bound states on transport properties of two- dimensional quantum spin Hall insulators. The bound statesare found able to induce quantum percolation in the or...
The macroscopic mechanical properties of colloidal particle gels strongly depend on
the local arrangement of the powder particles. Experiments have shown that more
heterogeneous microstructures exhi...
Percolation-to-hopping crossover in conductor-insulator composites
Percolation-to-hopping crossover conductor-insulator composites
2010/11/17
Here, we show that the conductivity of conductor-insulator composites in which electrons can
tunnel from each conducting particle to all others may display both percolation and tunneling (i.e.,hoppin...
