Ion Temperature in Inductively Coupled Plasmas (ICPs)

October 22, 2014

When modeling plasmas, various options exist for choosing an ion temperature. Your choice, however, may strongly influence your model’s results. Let’s discuss the theoretical reason behind this phenomenon and study an example involving an inductively coupled plasma (ICP) to illustrate the influence the different ion temperature options have on your model’s results.

Electron Energy Distribution Function

August 4, 2014

The electron energy distribution function (EEDF) plays an important role in plasma modeling. Various approaches can be used to describe the EEDF, such as Maxwellian, Druyvesteyn, or using a solution of the Boltzmann equation. Today, we will demonstrate the influence the EEDF has on a plasma model’s results. Additionally, we present a way to compute the EEDF with the Boltzmann Equation, Two-Term Approximation interface.

Microwave Plasmas

December 11, 2013

Microwave plasmas, or wave-heated discharges, find applications in many industrial areas such as semiconductor processing, surface treatment, and the abatement of hazardous gases. This blog post describes the theoretical basis of the Microwave Plasma interface available in the Plasma Module.

AltaSim Takes on Surface Plasmon Resonance Modeling

April 26, 2012

We’ve just got another finished article and layout back for COMSOL News and it looks as great as the others, but for different reasons. We usually ask a couple of our partners to write an article for COMSOL News to provide users with some more technical background to modeling. AltaSim Technologies, who are certified consultants and even run courses in COMSOL, have written an article about surface plasmon resonance.
