Single-molecule Electronic Devices
With miniaturization increasing in the field of information technology, the idea of using single molecules as tiny electronic components is becoming ever more appealing. Researchers at the Peter Grünberg Institute are studying the quantum transport properties of such molecules.  Using methods from theoretical physics, such as quantum field theory and statistical mechanics, they investigate, for example, magnetic molecules such as metallic-organic complexes. When electric or magnetic fields are applied, these molecules react with charge, spin and vibrational excitations.  A better understanding of the resulting effects and their interplay could make a variety of novel technical applications possible.  The above image illustrates the effect of the vibration of a molecular device on its conductance.
