摘要：
A photodetector is provided, including an active layer configured to generate charge carriers of a first type and of a second type by absorption of electromagnetic radiation; a first electrode configured to collect the charge carriers of the first type; and a second electrode configured to collect the charge carriers of the second type, the first electrode including a layer configured to collect the charge carriers of the first type, the layer including self-assembled monolayers, and nanowires comprising metal and functionalized by the self-assembled monolayers, the self-assembled monolayers of the layer are configured to functionalize the nanowires and to modify a work function of a material forming the nanowires. A method for manufacturing a photodetector and an electrode for a photodetector are also provided.
