Spin Lifetime in Electron-Doped InP Quantum Dots

Spin Lifetime in Electron-Doped InP Quantum Dots

Spin relaxation of electrons doped in InP quantum dots was studied by means of luminescence pump-probe and Hanle measurements. Optical pumping makes spins of doped electrons to be oriented in parallel to the helicity of the circularly polarized excitation. The luminescence pump-probe showed the spin orientation of the doped electrons …
