Our new article on a single spin crossover (SCO) molecule device is published in the Journal of Physical Chemistry (see “Multilevel Resistance Switching and Enhanced Spin Transition Temperature in Single and Double Molecule Spin Crossover Nanogap Devices“)
This work demonstrates spin-state dependent conductance switching in a unique, single-molecule spin crossover (SCO) device in which the SCO molecule is specifically tailored for surface deposition. In contrast to previously published work this paper uniquely demonstrates a temperature dependence of the switching mechanism. We also demonstrate an enhanced spin transition temperature compared to the bulk SCO material and multilevel resistance switching, signifying the presence of two SCO molecules across the junction. Behavior such as this, when controllable, could facilitate multi-level resistance switching and the development of ultra-small (single molecule) memory devices having more than two binary states.
