Contacting Molecules - Chemistry in Molecular Electronics

The study of the basic electron transport mechanism through molecular systems has been made accessible by fabrication techniques that create metallic contacts to a small number of organic molecules. In my talk, I will discuss some of the groundbreaking discoveries such as the measurement of the conductance through a single molecule using a break junction, the demonstration of molecular diodes/transistors, and molecular-scale systems that show reversible switching behavior. Despite these exciting discoveries new theoretical and experimental studies show that molecular devices are extremely sensitive towards the nature and quality of the contacts. Questions such as: (i) what does the contact look like, (ii) is the contact changed by the electronic measurement, (iii) is the contact stable over... Show More
