Application of Micro/Nanofabrication Techniques to On‐Chip Molecular Electronics

Abstract

Molecular electronics is a promising subject to overcome the size limitation of silicon‐based electronic devices. In the past decades, various micro/nanofabrication techniques have been developed for constructing molecular junctions, and a number of breakthroughs are made in the characterizations and applications of the single‐molecule device. The history and progress are reviewed in this article, laying emphasis on the recent works on the combination of micro/nanofabrication techniques with other techniques such as electrochemical deposition and surface‐enhanced Raman spectroscopy (SERS). Some prototypical single‐molecule devices such as molecular transistors are presented. Finally, the challenges and prospects in the fabrication of single‐molecule devices are discussed.

Electrochemical Potential‐Driven High‐Throughput Molecular Electronic and Spintronic Devices: From Molecules to Applications

“…In recent times,flexible devices have gained considerable attention in comparison to silicon-based electronic devices as they can offer variable-temperature operation, mechanical flexibility,w ide-area coverage,a nd cost reliability. [117][118][119][120] In this context, the McCreery group has fabricated ah ighly robust, stable,and wide-temperature-range endurable molecular junction on electron-beam-evaporated carbon (abbreviated as eC) on af lexible and semitransparent, polyethylene terephthalate (PET). [121] Diazonium salts of anthraquinone (AQ) were electrochemically grafted to form molecular layers of thickness 2.0-5.5 nm, followed by deposition of carbon/Aut op contact (Figure 9a-c).…”
