I'm a physicist learning crystallography and surface science on the side of my research and I came across the concepts: surface reconstruction in hexagonal materials, unit mesh of surfaces, etc.
I was given problems to solve but they are too advanced for me. These are based on the book Modern Techniques of Surface Science 3rd ed. by Dr. Woodruff.
Can someone advise me with some other sources of information to better understand Lattice Planes and Miller Indices, to the level shown in the Cambridge website.
