Spintronics, an exploration of spin properties instead of or in addition to charge degrees of freedom, holds promise to continue device miniaturization in the postsilicon era and beyond the age of Moore’s law. The benefits of spintronics come from the fact that there is no need for electric current to retain spin, and there are many paths to change spin without massively moving electrons. CONTENTS

During the past 15 years a new field has emerged, which combines superconductivity and spintronics, with the goal to pave a way for new types of devices for applications combining the virtues of both by offering the possibility of long-range spin-polarized supercurrents. Such supercurrents constitute a fruitful basis for the study of fundamental physics as they combine macroscopic quantum coher...

Molecular electronics [1] aims to use molecules as building blocks for the fabrication of electronic components—diodes, switches, transistors, and the like. At the heart of this idea is the possibility of synthesizing organic molecules with tailored properties, manipulating their electronic structure and optimizing their binding to different surfaces. Devices as small as a few molecules might l...
