摘要
We present an experimental realization of dielectric breakdown in disordered media by means of a random network made of resistors (concentration p) and diodes (concentration 1-p). The diodes are considered as elements which become conductors for a voltage greater than a specific value. Near the percolation threshold we find that the critical exponent of the breakdown voltage is greater than that of the correlation length. Using light-emitting diodes, we can display the breakdown paths and determine their properties.
