Fast-Response Photonic Device Based on Organic-Crystal Heterojunctions Assembled into a Vertical-Yet-Open Asymmetric Architecture

Researchers propose a general strategy to simultaneously connect multiple nanowire/microplate crystals heterojunctions with honeycomb-shaped asymmetric nanoelectrodes to explore their photovoltaic properties. The researchers have self-assembled N,N'-dioctyl-3,4,9,10-perylenedicarboximide (PTCDI-C8) n-type crystalline nanowires (CNWs) as model system to demonstrate the device design by mastering a method which relies on phase transfer (PT). The greater crystalline nature and rigidity of PT-CNWs enables their integration in the nanomesh through the formation of a physical contact specifically only with the upper electrode while forming an air gap with the bottom electrode.
