Provided are multimaterial devices, such as coaxial nanowires, that effect hot photoexcited electron transfer across the interface of the materials. Modulation of the transfer rates, manifested as a large tunability of the voltage onset of negative differential resistance and of voltage-current phase, may be effected by modulating electrostatic gating, incident photon energy, and the incident photon intensity. Dynamic manipulation of this transfer rate permits the introduction and control of an adjustable phase delay within a device element.
