The Electrical Properties And Microstructure Of An Ion Beam Mixed Metal-Polymer System
… decreases with increasing metal layer thickness. Coulomb gap and thermal Hopping theories are used to fit the experiment data. The results show the thin Cr layer samples more like Coulomb gap conducting materials; the thick Cr layer samples more in the Hopping conducting regions. A possible model …

Charge Transport Physics of Organic Semiconductors at High Carrier Densities
… transfer characteristics reveal a frozen Coulomb gap, whereby the non-equilibrium transport signatures of the charge carriers can be investigated. We attribute the formation of the frozen Coulomb gap to the freezing of the ionic motions. We demonstrate that these many-body effects are not …

Electron Tunnelling Study of High-Temperature Superconductors
… method for measuring a superconductor’s energy gap, and historically has provided important evidence for the microscopic mechanism of superconductivity in conventional metals. It was hoped that electron tunnelling would prove equally successful in revealing the mechanism of superconductivity in …

Non-Equilibrium Relaxation Dynamics in Disordered Superconductors and Semiconductors
… superconductors and charge carriers in the Coulomb glass in disordered semiconductors. We utilize an elastic line model to simulate magnetic flux lines in disordered type-II superconductors by performing Langevin molecular dynamics simulations. We study the non-equilibrium relaxation …
