Measuring Charge Transport in an Amorphous Semiconductor Using Charge Sensing

, 2009
We measure charge transport in hydrogenated amorphous silicon (a-Si:H) using a nanometer scale silicon MOSFET as a charge sensor. This charge detection technique makes possible the measurement of extremely large resistances.

Surface flashover in 50 years: Theoretical models and competing mechanisms

High Voltage, 2023
Surface flashover is a devastating electronic avalanche along the gas–solid interface when a high electric field is applied, which is a potential issue that threatens the safe operations of advanced power electronic, electrical, and spacecraft ...

Quantum Transport in Molecular Rings and Chains

, 1999
We study charge transport driven by deformations in molecular rings and chains. Level crossings and the associated Longuet-Higgins phase play a central role in this theory.

Charged solitons in branched conducting polymers

, 2018
We consider dynamics of charged solitons in branched conducting polymers. An effective model based on the sine-Gordon equation on metric graphs is used for computing the charge transport and scattering of charge carriers at the polymer branching points ...

Spin Transport in a Mott Insulator of Ultracold Fermions

, 2019
Strongly correlated materials are expected to feature unconventional transport properties, such that charge, spin, and heat conduction are potentially independent probes of the dynamics.

Two distinctive regimes in the charge transport of a magnetic topological ultra thin film

New Journal of Physics, 2020
The effect of the magnetic impurities on the charge transport in a magnetic topological ultra-thin film (MTF) is analytically investigated by applying the semi-classical Boltzmann framework through a modified relaxation-time approximation.

Charge Carrier Transport in Metal Phthalocyanine Based Disordered Thin Films

, 2006
The charge carrier transport in metal phthallocyanine based disordered thin films has been investigated. Charge carrier mobility in these disordered thin films strongly depends on the electric field and temperature due to hopping conduction.
