Self-Assembled Molecular Spin Arrays for Computation
Abstract
In the initial part of the project experiments were carried out to prepare a lattice of electron spins based on a self-assembled monolayer of an electron accepting molecules. In the first period we reported that a combination of quantitative infrared vibrational spectroscopy and density functional theory indicate that the addition of vapor alkali metal atoms to a self-assembled monolayer of a nitroaromatic molecule can create a spin lattice with -1 nm spacings between the electron spins. This appeared to be the first example of a molecular spin lattice and work was done to characterize the molecular structures. In the later stages of the project the work was done in more detail and it was shown that complications with accurate dose measurements of the deposited vapor made the interpretations less straightforward than originally thought. Efforts also were made to build an apparatus for measuring sticking coefficients and to bring on line XPS and scanning probe capabilities for the experiments.
