We wish to (i) prepare transition metal dichalcogenides TMDs (MoS2 and other members such as MoSe2, WS2 and WSe2) nanosheets covalently functionalized with electroactive molecules, (ii) transfer efficiently these functional layers to substrates and (iii) control finely the charge/spin transport/transfer properties of these hybrid systems via a bias voltage and the thickness of sheets.
Electron transport properties of the 2D materials will be characterized at the nanoscale by several SPM approaches. Electrode/2Dmat/electrode structures will be studied by conducting AFM to assess the electronic properties (HOMO, LUMO, work function, interface energy barrier) of the 2Dmat and electrode/2Dmat interfaces as a function of the nature and redox state of the immobilized molecules. Then, spin-dependent transport properties (2Dmat on FM electrodes) will be characterized in UHV by SPM down to 1.5K with a magnetic field up to 3T (SPECS JT-AFM/STM). These experimental results will be compared to ab-initio calculations of the electronic structure of 2Dmat.
The experimental post-doc will participate to device fabrication and electrical
characterizations. This person must be a physicist with backgrounds in SPM
characterization and/or electrical measurements and/or physico-chemical characterization.
