Project title:

Analysis of spin cooperativity and low dimensionality effects in bistable molecular compounds with applications in nanoelectronics.

PI: Aurelian ROTARU

Abstract:

Bistable molecule-based materials whose electronic and magnetic properties can be controlled by various external physical stimuli have attracted great attention because of their potential applications in different technological areas.
An important type of such molecular materials is spin crossover (SCO) materials which are planned to be addressed in this project.
Because of the clear change of properties, especially the color and magnetic characteristics, along with the conversion between two different electronic spin states, these materials are aimed to be used in nanoelectronics as information storage media, molecular switches, sensors, or displays. Since these materials are very sensitive to these changes, it could also be used to create sophisticated measurement tools, or optical filters capable of modifying the information contained in light beams, for example in telecommunication applications.
On the other hand, the miniaturization of the new generation of multifunctional materials towards the nanometric scale, in order to insert them into electronic devices opens new research subjects in the spin transitions field. One of the most interesting problems is the effect of the size reduction of the systems onto the cooperative effect.
This project is dedicated to the study of fundamental processes at the basis of the switching in spin-transition materials, with the aim to elaborate a protocol for the use of the bistable molecular systems as information recording media.
