Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Brillouin zone | Statement: [Léon Brillouin, notableConcept, Brillouin zone]

Target entity: Brillouin zone
Context triple: [Léon Brillouin, notableConcept, Brillouin zone]

• A. Brillouin zone chosen
  The Brillouin zone is the fundamental region of reciprocal space in a crystal lattice, defining the allowed wavevectors for electrons and underpinning the structure of electronic band diagrams.
• B. Wigner–Seitz cell
  The Wigner–Seitz cell is a primitive region of space in a crystal lattice that contains all points closer to a given lattice point than to any other, serving as a fundamental building block in solid-state physics and crystallography.
• C. Fermi surface
  The Fermi surface is the boundary in momentum space separating occupied from unoccupied electron states at zero temperature, crucial for determining a metal’s electronic and superconducting properties.
• D. Bloch waves
  Bloch waves are quantum-mechanical wavefunctions that describe particles, such as electrons, propagating through a periodic crystal lattice and form the basis for understanding electronic band structure in solids.
• E. Peierls–Nabarro model
  The Peierls–Nabarro model is a theoretical framework in solid-state physics that describes the behavior and motion of dislocations in crystal lattices by accounting for the periodic atomic potential.
• F. None of above.
• G. Unsure - the case is ambiguous/there is not enough information to decide.
