DEVICE INCLUDING SEMICONDUCTOR NANOCRYSTALS & METHOD

摘要

A method of making a device comprising semiconductor nanocrystals is disclosed. The method comprises forming a first layer capable of transporting charge over a first electrode, wherein forming the first layer comprises disposing a metal layer over the first electrode and oxidizing at least the surface of the metal layer opposite the first electrode to form a metal oxide, disposing a layer comprising semiconductor nanocrystals over the oxidized metal surface, and disposing a second electrode over the layer comprising semiconductor nanocrsytals. Also disclosed is a device comprising a layer comprising semiconductor nanocrystals disposed between a first electrode and a second electrode. A device can be a light-emitting device. A device can be a photodetector.
