Welcome to Petrou Lab
Current research effort focuses on the study of electrical spin injection in spintronic devices. A variety of optical techniques in the visible and near-infrared are used: reflectivity, absorption, photoluminescence (both continuous wave and time resolved) and electroluminescence spectroscopies. The experiments are carried out at liquid helium temperatures in magnetic fields up to 7 Tesla. The spin injection efficiency is determined from the optical spectra and the various spin-flip mechanisms are investigated.
