I'm in the process of fabricating colloidal quantum dot LED using layer by layer deposition. I wish to characterize the hole transport layer and electron transport layer before fabricating the device.
I have fabricated an all-inorganic QLED with FTO/NiO/CdSeZns/ZnO/Al. It has three conduction regions corresponding to Ohmic, Trap limited and space charge limited (SCLC). I expect the device to...
