PHYS 541, X-Ray diffraction and its applications
Phys 541 (X-Ray diffraction and its applications)
Aims:
The student should get acquainted with the fundamentals of x-Ray Diffraction (XRD) and its applications. He/She should be able to apply this course in his/her future research work, as XRD is the basic tool in studying the structural properties of materials.
