I have single crystalline film of SiC of Rhombohedral structure. I want to calculate the lattice constant of SiC but I am not able to determine the angle.
I think simply you can JCPDS data for your sample, which will give all the information, instead of doing manual calculations. Although one should the manually also.
Dear Suhail, I have already done the calculations using X-pert Highscore but I want to cross verify my data by doing it manually. If u can suggest the way that how to calculate lattice constant for Rhombohedral structure, It would be a great help.
