In this work, size effects on hopping conduction have been investigated for Si nanocrystal films. The measurement results fit a hopping percolation model well. Experimental results demonstrate that the nanocrystal dimensions influence on the hopping energy greatly via the activation energy and decay length. We also found that hopping energy can be reduced by H2 annealing treatment.

Recent developments have provided us with a simple but formally rigorous description of the asymptotic behavior of the correlation functions in charged molecular fluids. We present here a brief account of the application of this approach to small rod‐like molecular electrolytes solutions with their corresponding atomic counterions. The asymptotic length scales (decay length and wavelength) of the structural correlations are analyzed using the formalism of the dressed interaction site theory (DIST). The correlation functions are determined using the reference interaction site model (RISM) equation complemented with a suitable closure relation.

Jet flavor identification in multi-TeV e+e− collisions is expected to provide insights on new phenomena at scales beyond those probed by the LHC. The anticipated high track density and jet collimation represent a new challenge to jet tagging algorithms. A method, based on the sampling of the jet charged multiplicity, sensitive to the long decay length and large decay multiplicity of heavy flavor hadrons is proposed and the expected performances for the tagging of e+e−→bb events at s=3 TeV are discussed.
