abstract = "Here, evidence for field-aided and photogenerated carrier scattering between the Γ and L valley coupled with L-valley transfer at the absorber/barrier heterointerface in a GaAs/Al0.16Ga0.84As p-i-n diode is presented. A combination of time-resolved and CW photoluminescence is used to probe hot carrier transfer via emission from the high energy Al0.16Ga0.84As barrier after excitation in the GaAs absorber. These data demonstrate transfer of hot carriers between the satellite valleys of the constituent materials in this architecture. The achievement of L valley transfer is an important step towards the realization of a valley photovoltaic device.",
