Isotope-Purification-Induced Reduction of Spin-Relaxation and Spin-Coherence Times in Semiconductors

In two-dimensional hole systems, the Rashba spin-orbit interaction leads to a spin-dependent momentum. A perpendicular magnetic field spatially separates holes with different spins, creating mass spectrometer for spin. Spin-resolved focussing has been used measure spin polarization from amplitude of peaks. this work, The authors show that ${k}^{3}$ form term semiconductor changes scattering rate, which an exponential effect on peak amplitude. This result further demonstrates impact in physics.
