The Boltzmann Equation, Two-Term Approximation Interface
In a previous blog post, we introduced readers to different kinds of electron energy distribution functions (EEDFs) and their importance in plasma modeling. Today, we focus our attention on the Boltzmann Equation, Two-Term Approximation interface, demonstrating its use with an example from our Model Library.
Thermodynamic Equilibrium of Plasmas
Plasmas can exhibit a large variety of properties. There are plasmas with high and low ionization degrees, as well as those with high and low pressures and hot and cold temperatures. Different equations and modeling approaches are necessary for each kind of plasma. This blog post gives an overview of the different plasma types and shows when to use which of the interfaces available in the Plasma Module. Editor’s note: This post was updated on September 17, 2021, to reflect […]
Ion Temperature in Inductively Coupled Plasmas (ICPs)
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
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, 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.
In its natural state, air is a good insulator. However, if it’s adequately ionized, it can ultimately lead to “corona discharge”. What does that mean and why is it important? Let’s find out.
AltaSim Takes on Surface Plasmon Resonance Modeling
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.
