Story summary
  • The Nelder–Mead simplex method optimizes the optical absorption coefficient in Quantum Dot (QD) infrared photodetectors.
  • This algorithm effectively handles non-smooth functions and costly computations.
  • QD structures feature ten layers of self-assembled InAs within a GaAs barrier, tailored for various QD shapes.
  • The optical absorption coefficient uses a Hermitian Hamiltonian matrix based on effective mass theory.
  • The optimization aims to maximize bound-to-bound absorption coefficients for infrared spectroscopy.
