In a face centred cubic of a and b
WebAug 26, 2024 · Base-centered means you get the same lattice back if you translate the corners of each unit cell to the centers of a pair of specified opposing faces (the "bases"). But "cubic" means you get the same unit cell back when you rotate each face to match an adjacent one (rotating around a body diagonal of the cube). WebMar 22, 2024 · The precise control of molecular self-assembly on surfaces presents many opportunities for the creation of complex nanostructures.
