Classical and quantum transport calculations for elastically scattered free electron gases in 2D nanostructures when B=0
The Boltzmann equation in the relaxation time approximation is used to calculate formal expressions for the local electrical, thermal and thermoelectric transport coefficients of a strictly 2D, elastically sca...

Hop** Transport in One-Dimensional Semiconductor Systems
The channel conductance of a one-dimensional MOSFET shows reproducible irregular structure as a function of gate voltage when the device is operated near threshold at low temperatures. The voltage scale on whi...

Hop** Conduction in n-GaAs at High Frequencies and High Magnetic Fields
The hop** conductivity of n-GaAs is studied using n+n n+ mesa structures, with the n layer about 1 μm thick, for frequencies up to 100 MHz and magnetic fields up to 5T. Results are discussed in terms of recent ...

Epa Analysis of Frequency Dependent Loss Data For a-Ge and a-Si
There have recently been several improvements of ac Hop** conductivity theory. Movaghar and co-workers 1,2 Develop a rndom walk model. In the “extended pair approximation” Summerfield and Butcher3,4 analyse the...

Random walks on random lattices
The salient features of random walks on random lattices are described and contrasted with those of simpler random walks. The dispersion of an injected carrier sheet is discussed for the case when the ac mobili...
