• nanoelectrodes separated by gaps of 8 to 20 nm. They are fabricated by electron beam lithography (EBL) in a lift-off process while using a self-aligned Al2O3 hard mask to define the nanogap size [20][21]. The resulting nanoelectrode pairs are used for the on-chip preparation of Ru(TP)2-complex wires according to

For this purpose, the transport properties of the redox-active Ru(TP)2-complexes are studied under electrical or optical triggering in Ru(TP)2-complex wire devices and in Ru(MPTP)2–AuNP devices. Both devices are based on the same nanoelectrode design and are composed of analogous

Nanodevice fabrication The fabrication of nanoelectrode samples, each equipped with twelve nanoelectrode pairs (consisting of an AuPd and a Pt electrode with a nanometer-sized gap in between), was performed according to a recently described process

One of the promising

• approaches for the preparation of such systems is templated electrodeposition. In the present study, porous anodic alumina templates are used to prepare Au nanoelectrode arrays. Multistage electrodeposition is proposed for the formation of recessed electrodes with the ability to tune the distance between the

• surface of the porous template and the top surface of the nanoelectrodes. A set of complementary techniques, including chronoamperometry, coulometry, and scanning electron microscopy, are used to characterize the nanoelectrode arrays. The number of active nanoelectrodes is experimentally measured. The
