Overview

This study reports momentum density profiles in AlBi, InBi, and GaBi using positron annihilation, suggesting new insights into their charge distributions.

Key Points

  • Initial results reveal a distinct asymmetrical positron charge distribution, indicating charge density variations.
  • Positron density peaks in open interstices, indicating shielding from ion cores and valence bonds.
  • Momentum densities for (001, 110) planes are calculated to analyze positron interactions in the semiconductor compounds.
  • The computational method aids in interpreting k-space densities from experimental positron annihilation data.
