TFYA23 Crystal Growth Technology, 6 ECTS credits.
/Kristalltillväxt teknologi/

For:   Fys   MPN   Y  

 

Prel. scheduled hours: 26
Rec. self-study hours: 134

  Area of Education: Science

Subject area: Physics
  Advancement level (G1, G2, A): A

Aim:
The overall aim of this course is to give a general introduction to fundamental principles for growth of semiconductor and optical crystals with suitable characteristics for production of components. In addition to that, advanced growth techniques will be demonstrated and the students will have the unique possibility to combine theoretical knowledge with practical applications. This course is connected to the research activities on crystal growth that are carried out at IFM in close cooperation with Swedish industry, e.g. the company Norstel AB (Norrkoping), etc. This means that the students will be expected to do the following after completing this course:
  • Have knowledge and be able to utilize thermodynamics relations in crystal growth.
  • Define basic principles of phase transition and motivate the choice of growth methods for different materials.
  • Apply theoretical background to analyze crystal growth mechanism in different material systems.
  • Predict material properties through knowledge of different growth methods.
  • Use knowledge of crystal growth methods in order to solve problems within physics, chemistry and material science areas.
  • Calculate parameters and design crystal growth systems.
