Thermal non-equilibrium transport in colloids

Non-Equilibrium Transport

Suppose we flow through an adsorption or chromatograph column so fast that the adsorption is not at equilibrium at a given point in the column. This departure from equilibrium could be either due to diffusion resistance within the porous particles of the column or due to kinetic limitation of the adsorption process. Alternatively, you may wish to separate different size macromolecules by the di...

Non-equilibrium Thermal Effects in Power Transistors

This work addresses electro-thermal simulation of LDMOS devices and associated non-equilibrium effects. Simulations have been performed on three kinds of LDMOS i.e. bulk Si, partial SOI and SOI, with a view to compare the extent of non-equilibrium in each. Phonon temperature contours and electron energies were analyzed in each case. The results indicate that, under similar operating conditions,...

Thermal Fluctuations in Non-Equilibrium Thermodynamics

Thermal fluctuations in fluids and fluid mixtures in stationary nonequilibrium states are spatially long ranged. This long-ranged nature of the non-equilibrium fluctuations is caused by a coupling between hydrodynamic modes through the non-equilibrium fluxes or gradients. The phenomena are discussed with some illustrative examples in fluids and fluid mixtures.

Non-equilibrium quantum dots: transport

The electronic transport through three-dimensionally confined semiconductor ’quantum dots’ is investigated and analyzed. The spectrum corresponds to resonant tunneling from laterally confined emitter contact subbands through the discrete three-dimensionally confined quan tum dot states. Momentum non-conservation is observed in these structures.
