The letter first presents the electrical properties of a GaP-based PIN diode, in particular the reduction of the characteristic resistance of the p-contact, thanks to a judicious combination of metal choice and thermal annealing. Secondly, carrier injection in the active area is investigated by use of time-resolved photoluminescence, regarding particularly the nature and composition of the barrier and quantum wells materials, with a focus on the nitrogen incorporation issues
