An analogue of the speckle contrast technique for low-conducting features enhancement in scanning tunneling microscopy images of nanocomposites

An analogue of the speckle contrast technique for low-conducting features enhancement in scanning tunneling microscopy images of nanocomposites

Basing on the dependence of tunneling current fluctuations on the local conductivity of a non-uniform media, we propose to apply the computational technique mathematically equivalent to the speckle contrast calculations for pattern recognition in low-contrast images obtained via the scanning tunneli...
