Embodiment Construction

[0019] Specific embodiments are now discussed in detail which illustrate the best mode presently believed by applicants to carry out the invention. Alternative embodiments where applicable are also briefly described.

[0020] In accordance with the teachings herein, there is provided a composition of matter that produces electronic switching by intermolecular, or intramolecular charge transfer, or by charge transfer between a molecule and an electrode, the charge transfer being induced by an electric field. The goal is to switch molecules / molecular complexes between low and high conductivity states. The idea is to induce charge transfer to / from the molecule by applying an external electric field, causing the molecule to gain or lose charge and thus change its conductivity. This composition of matter allows the preparation of non-volatile devices that retain their charge and changes in electrical properties when the external electric field is removed.

Abstract

A composition of matter is provided that results in a change of electrical properties through intra-molecular charge transfer or inter-molecular charge transfer or charge transfer between a molecule (12) and an electrode (14, 16; 14', 16'), wherein the charge transfer is induced by an electric field.

Description

technical field [0001] The present invention relates to molecules and molecular systems for realizing electronic and optical switching at the nanoscale, such as in switches, sensors and transistors. Background technique [0002] Molecules and devices have previously been integrated to create molecular transistors in which charge and electrical properties change when an external electric field is applied across the molecule. In these molecules, the change in charge and electrical properties within the molecule disappears after the electric field is removed. Therefore, it is impossible to fabricate non-volatile devices using these molecules or device structures. [0003] There is a need for a method to fabricate non-volatile devices in which changes in charge and electrical properties are maintained when the external electric field is removed. Contents of the invention [0004] According to embodiments disclosed herein, there is provided a composition of matter that produc...
