ECE 523: Gaseous Electronics and Plasmas 
`
`Spring 2016 
`
`Instructor: J. Gary Eden, 2042 ECE Building, email: jgeden@illinois.edu 
`
`TA: Jimmy Ni, 2038 ECE Building, email: hni2@illinois.edu 
`
`Office hour: Tuesday after class, 2:00 – 3:00 ECEB seminar room. 
`

`
`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:
