MME ANNE-MARIE GONCALVES 

Research topics

Fundamental (Photo)electrochemistry researches at semiconductors (III-V, Si,…), metals (Au, Pt, …) interfaces in aqueous
and non-aqueous solvents (DMF, CH₃CN, …) with a strong expertise in liquid ammonia (P_atm, -55°C)
 

• Understanding of solvents contributions on interfacial electrochemical mechanisms (dielectric constant, viscosity, pH scale, chemical intermediates stability (i.e radicals…))
• Performing the reactivity of solvated electrons in liquid ammonia (i.e using Pt microelectrodes as internal probe)
• Understanding fundamental interfacial reactions (passivating films, hydrogen evolution, oxygen reduction, metal electrodeposition…)
• Determination of semiconductor’s diagram energy evolution (impedance measurements, lock-in amplifier, photoluminescence…)
• Monitoring electrode surface/interfaces modifications (impedance measurements, photoluminescence, quartz crystal microbalance, chronopotentiometry, Pt microelectrodes as internal probes, disc ring, wettability by angle contact, XPS, p-ARXPS, MEB-TEM…)

Towards applied researches and surface treatments of (opto)electronic devices
 

• Electrochemical treatments of (opto)electronic devices in liquid ammonia in collaboration with C2N (DR. J.L. Pelouard) : i.e New strategies of selective pattern dissolution
• Validation of modified electrodes transfer in clean rooms (elaboration of thin masks)
• Electrochemical engineering for the detection of metal impurities on supporting electrodes
• Since 2012, 4 patents and 6 international extensions
