Chemical Self-Assembly Strategies Toward The Design Of Molecular Electronic Circuits, Dustin Olson

Theses and Dissertations

The field of molecular electronics is generally divided into one of two major categories, the first focusing on the unique functionalization of single molecules to produce electronic behavior, the other utilizing large assemblies of molecules to produce electronic behavior. The former approach is largely attributed to the seminal paper by Aviram and Ratner in which they proposed a molecular donor-bridge-acceptor (D-B-A) type architecture could lead to single molecule rectification producing electronic effects similar to conventional semiconductor based diodes. Extensive research has been carried out in both fields as it is foreseen that new approaches to electronics miniaturization will be necessary …

Electrical Measurements And Attenuated Total Reflection Infrared Spectroscopic Study Of Aromatic Isocyanides And Thiols On Gold, Rasha Khaled Abuflaha

Theses and Dissertations

In 1947, Bell Laboratories produced an amplifier design in which an electric field would enhance the flow of electrons near the surface of a layer of silicon, it was called the “point-contact transistor”, the world’s first semiconductor amplifier. In order to minimize the electronic circuit elements (device miniaturization), the ability to utilize single molecules that function as self-contained electronic devices (molecular electronics) has motivated researchers around the world. Molecular electronics investigates single molecules and collections of molecules assembled into electronic circuits. Currently, semiconductor devices are fabricated using a “top-down” approach that employs lithographic and etch techniques to pattern a substrate, …

Two seminal events are thought by many to be the birth of nanotechnology and molecular electronics. In 1959, Nobel Laureate Richard Feynman gave his famous "There's Plenty of Room at the Bottom" lecture to an American Physical Society meeting at Caltech. The transistor had been invented by Bell Laboratories in 1947, and already the race was on for device miniaturization. Feynman's lecture focused on some of …
