Order amidst disorder for two dimensional nanoribbons with various boundary conditions

Abstract We show quantum systems with disordered Hamiltonians may exhibit order in commonly measured quantities. This counter-intuitive situation is demonstrated using a conventional tight binding model for two-dimensional nanoribbons various boundary conditions. The analysis uses the traditional non-equilibrium Green's function (NEGF) methodology electron transport. study dragon nanodevices that amidst disorder. Each Hamiltonian nanodevice shows both bond currents and local density of states (LDOS) propagating electrons.
