Phrase: Gunn effect | Statement: [Esaki–Tsu relation, relatedTo, Gunn effect]

Target entity: Gunn effect
Context triple: [Esaki–Tsu relation, relatedTo, Gunn effect]

• A. Segré–Silberberg effect
  The Segré–Silberberg effect is a fluid dynamics phenomenon in which particles suspended in laminar flow through a circular tube migrate to stable equilibrium positions at a characteristic radial distance from the tube wall.
• B. Kapitza–Dirac effect
  The Kapitza–Dirac effect is a quantum phenomenon in which a beam of particles, such as electrons or atoms, is diffracted by a standing wave of light, demonstrating the wave-particle duality of matter.
• C. Rubin–Ford effect
  The Rubin–Ford effect is an observed large-scale motion of galaxies relative to the cosmic microwave background that provided early evidence for peculiar velocities and inhomogeneities in the universe’s expansion.
• D. de Sitter effect
  The de Sitter effect is a relativistic phenomenon in celestial mechanics describing how general relativity alters the motion and precession of orbiting bodies in a gravitational field.
• E. Event Horizon
  Event Horizon is a 1997 science fiction horror film about a rescue crew investigating a spaceship that disappeared into a black hole and returned with a malevolent presence.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Gunn effect
Triple: [Esaki–Tsu relation, relatedTo, Gunn effect]

The Gunn effect is an electronic phenomenon in certain semiconductors where negative differential resistance leads to high-frequency oscillations and microwave generation under strong electric fields.
