The 4 As atoms are la belled, All other atoms 'Ga' are As As .Lo.0,0) a The figure above shows the structure of GaAs. It is very similar to the diamond structure, but some of the atoms are Ga and some of them are As. (a) Define a set of lattice vectors and basis that can be used to describe the crystal structure. For the lattice, in additional to the three lattice vectors, please provide the name of the lattice (e.g. rhombohedral, simple cubic, face-centered cubic, body-centered cubic). For the basis, show the coordinate and the type (Ga or As) of the atoms. Note: There are multiple correct answers. However, you need to make sure that the lattice and basis together can fully describe the structure shown in the figure. (b) How many Ga and As atoms can be found in the lattice cell that you choose in part (a)? (c) Is the lattice cell you choose in part (a) a primitive cell? * The answers for (b) and (c) depend on the particular cell that you choose in part (a). くJ0 く The 4 As atoms are la belled, All other atoms 'Ga' are As As .Lo.0,0) a The figure above shows the structure of GaAs.
