Delocalization in infinite disordered two-dimensional lattices of different geometry
(Physical Review B, 2017-12-06)
The spectral approach to infinite disordered crystals is applied to anAnderson-type Hamiltonian to demonstrate the existence of extended states for nonzero disorder in 2D lattices of different geometries. The numerical ...
Simple experiment on the sputtering rate of solids in gas discharges
(Physics of Plasmas, 2017-06)
We present a very simple and sensitive method to measure the sputtering rate of solid materials in stationary low-pressure gas discharges. The method is based on the balance of the centrifugal force and the confinement ...
