Spin Polarization in InGaAs quantum dots for spin-optoelectronics.
New paper in Applied Physics Letter on how the efficiency of introducing a spin polarization in InGaAs quantum dots depends on pump wavelength. Unfortunately, the wavelengths for best spin polarization and best quantum efficiency are not the same. If you are interested, please look at Appl. Phys. Lett. 126, 191102 (2025).
