Abstract
The investigation of charge transport in organic nanocrystals is essential to understand nanoscale physical properties of organic systems and the development of novel organic nanodevices. In this work, we fabricate organic nanocrystal diodes contacted by rolled-up robust nanomembranes. The organic nanocrystals consist of vanadyl phthalocyanine and copper hexadecafluorophthalocyanine heterojunctions. The temperature dependent charge transport through organic nanocrystals was investigated to reveal the transport properties of ohmic and space-charge-limited current under different conditions, for instance, temperature and bias.
Highlights
Organic semiconductors have been widely applied in developing optoelectronic devices including light-emitting diodes, transistors, sensors [1,2,3]
The fabrication yield of the devices contacted by rolled-up electrodes on the single chip can achieve more than 95% owing to the reliable parallel nanofabrication when the whole process is carefully performed
To study the charge transport properties of the crystalline heterojunction nanopyramids, three kinds of organic nanopyramids were grown on well-defined bottom Au finger electrodes (Au mesa), i.e., pure VOPc (10 nm), F16CuPc (1 nm)/VOPc (9 nm) and F16CuPc (1 nm)/VOPc (8 nm)/F16CuPc (1 nm)
