Photocatalytic Deposition for Metal Line Formation

Abstract

AbstractIn neural systems, plasticity can be found throughout a variety of scales, ranging from local synaptic plasticity between two neurons towards long-range connections and global plasticity within larger neuron assemblies. While memristive devices have attracted a lot of attention as a potential neuromorphic analog to represent local synapses and are regarded as promising building blocks for neuromorphic engineering, long-range connections and globally mediated aspects like homeoplasticity are not yet widely considered for neuromorphic systems. In this chapter, photocatalytic deposition is discussed as an approach to form metallic structures from a global liquid reservoir. In this context, the photocatalytic properties of TiO2 thin films are employed to reduce metallic species from the surrounding solution. This chapter will elucidate the fundamental process of photocatalytic deposition with photocatalytic TiO2 thin films and will showcase the applicability towards the formation of metallic structures at the example of arrangements of locally grown metallic Au structures.
