  There is great interest in so-called nano-electronic devices due to the
furious rate of device miniaturization. Fabrication of micro and nano scale
resistors and capacitors have already been achieved steadily, but so far, there
has been little development in the way of nano-scale coil inductors. This is
because of the physical limitations in miniaturization of the design of a
solenoid with wires coiled around a metallic core. So, while transistors get
steadily smaller, basic inductors in electronics remained relatively bulky. Few
methods exist for creating conductive polymer coils and graphene-based kinetic
nano-inductors, but their large-scale fabrication process is complex and mostly
beyond the current commercial technology available. So, a simpler, scalable,
and robust fabrication technique is needed to overcome this bottleneck. In this
work we demonstrate a new technique consisting of the laser lithography using a
laser engraver of a (poly)vinyl alcohol (PVA)/graphene oxide film composite
which results in a large inductive effect. We attribute this behavior to the
formation of high curvature twisted screw dislocation type conductive pathways
composed of polyacetylene chains linked by pi-pi interactions to reduced
graphene oxide flakes resulting in inductive effect.
