Research topics

My research topics are centered on the observation of individual nanoobjects, and the measurement of their (electronic) properties, in order to understand the diferences between the mean behaviour of a collection of objects (absorbtion spectra of molecules in solution for instance) and the behaviour of one individual object.

Present


Conductance measurements on nanometric-sized molecular contacts


PI of the ANR project FOST, for FOur STate molecular device. In this project, we aim at extending the concept of conformational memory by synthesizing dedicated molecules with two addressable subunits that can undergo conformational changes upon irradiation and / or protonation. Such molecules would present 4 different electronic states (i.e 2 bits memory), that could be used for implementing basic logic function at the single molecule scale.
