Physics · Solid State Physics
The XRD pattern of a crystalline material, measured using Cu Kα radiation (λ = 1.54 Å), shows peaks at 2θ values of 38.43°, 44.65°, 65.02°, and 78.13°. Considering the cubic edge length is approximately 4 Å, the Miller indices and Bravais lattice of this material are:
- 1(111) (200) (220) (311), BCC
- 2(110) (200) (211) (220), FCC
- 3(111) (200) (220) (311), FCC✓
- 4(110) (200) (211) (220), BCC
Correct answer
(111) (200) (220) (311), FCC
