Executive Summary : | The era of miniaturization is driven by the growing need for energy and data transfer speed, leading to the development of new technologies such as Printed Electronic Devices (PEDs). These devices are fabricated on micro and nano scale, with circuit elements like LEDs, FET-MOSFETs, nano capacitors, nano-batteries, and even nano wires being explored. NWs are used in nano circuitries as a connecting entity, playing a significant role in fields like quantum computers, nanorobots, biosensors, and CMOS devices. They are isometric in shape, with dimensionality of a few nano meters and lengths up to a few microns. Controlled synthesis of NWs may open new doors in nanoelectronics. Silicone is currently the most popular element for NW fabrication, but processing involves high temperatures and often leads to defective NWs with kinks, bent shapes, or a sponge-like web. These drawbacks limit the future applicability of NWs but open new channels for finding materials that can be easily aligned and processed. Discotic liquid crystals (DLCs) are versatile materials with self-assembling and self-healing properties. They can form ordered arrangements similar to crystalline order by slow cooling, dewetting, and lithographical alignment at low temperatures. DLCs have π-π orbital stacking interactions among their molecules, allowing hopping charge transport through columnar discs along the length of columns. They show charge carrier mobility in the range of 0.2-10 cm²V-1s-1. Discotic liquid crystals are promising candidates for fabricating nano wires, overcoming the shortcomings of current nano wires in terms of conduction properties and easy processing. |
