Ion Energy Distribution Function

Application ID: 11400


One of the most useful quantites of interest after solving a self-consistent plasma model is the ion energy distribution function (IEDF). The magnitude and shape of the IEDF depends on many of the discharge parameters; pressure, plasma potential, sheath width etc. At very low pressures the plasma sheath is said to be collisionless, meaning that the ion energy is not retarded by collisions with the background gas. At higher pressures the ions collide with the background gas molecules in the sheath and their energy at the moment of impact with a surface is reduced. This model requires the Particle Tracing Module.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product's capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
