Overview

Laser Photoacoustic Methods Investigate Coherent Phonon Generation in InAs/GaSb Superlattices, Indicating Novel Control Techniques.

Key Points

  • The study aims to explore the generation and propagation of coherent phonons in InAs/GaSb superlattices.
  • Utilized laser photoacoustic techniques to investigate phonon behavior.
  • Focused on short-period InAs/GaSb superlattices grown on GaSb (001) substrates.
  • Applied femtosecond laser pulses to initiate coherent phonons.
  • Coherent phonons in the sub-terahertz frequency range were generated.
  • Phonons propagated at small angles to the (110) surface.
  • Interaction features with polarized electromagnetic radiation were identified, suggesting a new method for local control of crystalline structure.
