Electrodeposition of metals and liquid-gated field-effect transistors
Starting date: to be defined
Duration: 9 months
Supervisor: Prof. S. Casalini
Co-supervisor: Dr. N. Comisso, Prof. A. Cester
Scientific background: Cathodic electrodeposition allows the deposition of metal layers with different morphologies, ranging from compact to highly porous materials. Porous metals are deposited at highly negative potentials (i.e at high cathodic current densities) which induce two simultaneous reactions: i) hydrogen evolution depending on pH) and ii) metal ion reduction.
Liquid-gated field-effect transistors (LG-FETs) are electronic devices capable to be operated in aqueous solution. These devices offer a wide range of applications spanning from low-power e-units to portable sensors.
Main objective: This thesis will deal with the electrodeposition of metals onto the gate terminal of these electronic devices. Since the gate terminal is made of Au, more and less noble metals will be deposited and characterized. Furthermore, these LG-FETs will be
characterized electronically to evaluate the impact of the above-mentioned metal coatings onto the gate terminal.
Experimental work: This thesis offers an interdisciplinary activity, because it crosses the borders of chemistry, material science and electronic engineering. For these reasons, the student will work in three workplaces: i) Institute of Condensed Matter Chemistry and Technologies for Energy (ICMATE-CNR), ii) Department of Chemical Sciences (DiSC) and iii) Department of Information Engineering (DEI). Techniques used: i) electrochemical setup, ii) device fabrication (drop-casting, zone casting, surface functionalization, spin-coating etc.) and iii) device characterization.
