Sample interview questions: Describe your familiarity with the different crystal structures and lattices commonly observed in solidstate physics.
Sample answer:

Familiarity with Common Crystal Structures:

Cubic Structures:
 Simple Cubic (SC): The most basic cubic structure, where atoms are arranged at the corners of a cube.
 BodyCentered Cubic (BCC): Atoms are located at the corners and the center of a cube.
 FaceCentered Cubic (FCC): Atoms are located at the corners and the centers of the faces of a cube.

Hexagonal Structures:
 Hexagonal ClosePacked (HCP): Atoms are arranged in a hexagonal pattern, with each atom surrounded by six others.

Orthorhombic Structures:
 Simple Orthorhombic: Atoms are arranged with three different edge lengths.

Tetragonal Structures:
 Simple Tetragonal: Atoms are arranged in a square pattern, with two different edge lengths.

Monoclinic Structures:
 Simple Monoclinic: Atoms are arranged with three different edge lengths and one angle different from 90 degrees.

Triclinic Structures:
 Triclinic: Atoms are arranged with three different edge lengths and all angles different from 90 degrees.


Understanding of Crystal Lattice Dynamics:

Phonons: Quantized lattice vibrations that determine important properties such as thermal conductivity and specific heat.

Dispersion Relations: The relationship between phonon frequency and wave vector, which provides insights into lattice dynamics.


Expertise in Crystallographic Techniques:

Xray Diffraction (XRD): A nondestructive technique for determining crystal structure by analyzing the diffraction patterns of Xray beams.

Neutron Diffraction: Similar to XRD but uses neutrons instead of Xrays, providing complementary information.
