Overview

Randomized trial quantifies transport anisotropy in gallium-free infrared detectors, suggesting improvements for performance.

Key Points

  • To quantitatively evaluate the anisotropic transport of minority carriers in type-II superlattices for infrared detection.
  • Utilized AC-EBIC on mid-wave infrared T2SL photodiodes.
  • Analyzed EBIC amplitude and phase profiles to determine diffusion characteristics.
  • Applied a numerical diffusion model for fitting transport parameters.
  • Found transport anisotropy of 2.5 between lateral and vertical diffusion lengths.
  • Estimated vertical diffusion lengths of 3-4 μm and lateral lengths of 7-10 μm.
  • Determined minority carrier lifetime of 400-670 ns and surface recombination velocity less than 800 cm/s.
