Plasma Technology and Thin Films
This UC will provide a deep understanding of various deposition techniques using plasma technology and other technological applications, allowing students to become familiar with the fundamental scientific issues associated with these technologies in order to contribute to solving research problems. It is also intended to provide them with the skills associated with the doctoral degree, namely systematic understanding in the scientific domain, skills for research, critical analysis of concepts and results, implementation of projects, written and oral communication techniques, among others.

It is recommended to have in the basic training a curricular unit of Solid State Physics, Surface Technology and Interfaces or similar.
-“Physical vapor deposition of thin films ” – John E. Mahan, Wiley, 2000.
-“Introduction to plasma physics” – D. A. Gurnett and A. Bhattacharjee, 2nd ed., Cambridge University Press, 2017.
-“Physics of thin films ” – Maurice H. Francombe and John L. Vossen, ACADEMIC PRESS, INC., 1982.
This course will operate on the basis of tutorial sessions and works to be carried out and presented throughout the semester.
The final evaluation will be the average of the classifications obtained in the reports of the proposed and performed experimental works and a monograph.
