Particle-size control and patterning of a charge-transfer complex for nanoelectronics

A charge-transfer complex, copper tetracyanoquinodimethane (CuTCNQ), was used to control the particle size of micro- and nanostructures and to pattern a surface with micro- and nanostructures for potential nanoelectronics applications. CuTCNQ was synthesized by spontaneous electrolysis. The surface co-patterned with micro- and nanostructures exhibits hydrophobicity and can be used for constructing water/moisture-resistant and contamination-free electronic devices. CuTCNQ micro- and nanostructures can be grown vertically on Cu/indium tin oxide substrates, providing a good connection between the particles and electrodes of the device.
