`
`
`
`Goals of Course:
`
`This course addresses the fundamental science and technology of low temperature, partially ionized,
`non‐equilibrium plasmas. This class of plasmas is used, for example, for etching and deposition of
`materials, surface treatment, lighting sources, flat panel displays, and lasers. These plasmas also occur
`naturally in phenomena such as the aurora borealis and interstellar lasers. The objectives of this course
`are to first provide a foundation of the fundamentals of electron‐atom and electron‐heavy particle
`collisions, electron and ion transport, and the electron energy distribution function. After laying this
`foundation, the course will apply these fundamentals to the study of technologies which use partially
`ionized plasmas, with examples taken from lasers, plasma material processing, and lighting sources. If
`time allows, the physics of microplasmas will also be discussed.
`
`Grading policy:
`
`The topics being addressed in this course are inter‐ and cross‐ disciplinary. As a result, one will not fully
`benefit from the course without putting a good‐faith effort into the homework. To acknowledge the
`importance of homework, it is heavily weighted in the determination of the grade. The grading
`algorithm will be as follows:
