Comparison of Transport and Switching Characteristics of Ti/Molecule/Pt and Cr/Molecule/Pt Devices

ORAL

Abstract

Molecular devices that consist of a monolayer of stearic acid molecules sandwiched between Pt and Ti electrodes can be switched ``on'' and ``off'' reversibly. To gain insight into the switching and mechanism, we fabricated and measured similar molecular junctions by replacing Ti with chromium as the top electrode. These devices can be switched ``off'' controllably, but not ``on.'' The conductances of both types of devices display similar dependence on temperature. Latest data will be discussed in terms of various theoretical models.
