+ | **TASK_6 and TASK_7** | ||
+ | In TASK_6 and TASK_7 you will find scf.in and bands.in to compute the bandstructure of a 7AGNR nanoribbon | ||
+ | from it's primitive cell (TASK_6) and in a double cell (TASK_7 containing two units) | ||
+ | |||
+ | use | ||

+ | and | ||
+ | < | ||
+ | ./ | ||

+ | to plot teh bands in TASK_7. | ||
+ | |||
+ | Additionally in the TASK_6 directory execution of: | ||
+ | < | ||
+ | ./ | ||
+ | </ | ||
+ | will create a superposition of the two plots | ||
