Story summary

The Nelder–Mead simplex algorithm optimizes the optical absorption coefficient of Quantum Dot (QD) infrared photodetectors.
This method effectively handles non-smooth and computationally expensive functions.
QD structures feature ten layers of self-assembled InAs within a GaAs barrier, with geometries like semispherical and conical shapes.
The optimization targets bound-to-bound absorption coefficients for infrared spectroscopy.
The study highlights the need for improved photodetector optimization for better infrared sensing.
