Electron transport in a non-uniform magnetic field
Journal of Physics: Condensed Matter, 1995We have used MBE regrowth technology to produce a non-planar 2DEG at a GaAs/AlGaAs heterojunction grown over an etched facet. By applying a uniform magnetic field to this structure we obtain a spatially varying field component normal to the 2DEG. When the magnetic field is applied in the plane of the substrate, the resistance measured from one side of ...

Bubble growth in non-uniform temperature fields
Chemical Engineering Science, 1971Abstract A previous theoretical model for bubble growth in superheated liquids has been extended to non-uniform temperature fields. The growth rate has been assumed as controlled by heat transfer, surface tension, liquid inertia and non-equilibrium at the liquid—vapor interface.

Effect of non-uniform temperature field in viscosity measurement
Journal of Visualization, 2015In viscosity measurement, temperature control is very important. In this research, the effects of temperature distribution in viscosity measurement are investigated. Vibrational viscometers are preferred in experiments over other types of viscometers due to their low cost, easy to use and effective continuous viscosity measurement capability.

The Movement of Molecules in Non-Uniform Electric Fields
Australian Journal of Chemistry, 1961The motion of polar molecules as solute in a non-polar solvent, under the action of a non-uniform electric field, has received little attention. The theory of such motion has been developed and an experimental concentration separation of 25% achieved between p-nitroaniline and carbon tetrachloride from solution.

Criterion for spark-breakdown in non-uniform fields
Journal of Applied Physics, 2014We develop a criterion for spark-breakdown in non-uniform field geometries with positive polarity and small electrode separations so that breakdown evolves without the formation of a leader. We arrive at the spark-breakdown criterion by framing it in terms of gain and instability conditions, whose relative importance is established from an analysis of ...

On a chain suspended in a non-uniform gravitational field
Bulletin géodésique, 1974It is possible to simply describe the curve followed by a chain suspended in a non-uniform gravitational field. Parallel discussions are given using the two theories of gravitation, Newtonian and general relativistic.

The Townsend coefficient in non-uniform electric fields
Journal of Physics D: Applied Physics, 1991A one-dimensional model of electron multiplication in a gas is considered by using a system of equations of moments. An approximate expression for the first Townsend ionization coefficient is derived. It is shown that for a linearly decreasing electric field, the multiplication cannot be characterized by a local transport coefficient, such as Townsend ...

Equilibrium shapes in non-uniform fields of concentration
The Bulletin of Mathematical Biophysics, 1942The special case of a metabolizing cell, with infinite permeability, suspended in the field of an equivalent cell is treated exactly to determine its equilibrium shape for small deformations. It is found that flattening takes place along the line of centers.
