216th Meeting of ECSVienna, 4-9th October 2009 Sessions: F1 Current trends in Electrodeposition F5 Semiconductors, metal oxides … B9 Semiconductor Electrolyte Interface & Photoelectrochemistry Specific Lectures: Dieter Kolb (2009 Olin Palladium Award) John Stickney (2009 ECS Electrodeposition Div. Research Award) Rudiger Memming (Gerischer Award of the Eur. Section. NO lecture, but some interesting reminiscences!)
F1: Electrodeposition • Stickney: electrochemical atomic layer deposition • Deposition of compound semiconductors (CIGS): layer-by-layer growth • Others: • temporal/spatial organisation in electrodeposition (Nakanishi): growth of metal networks via oscillatory processes • protein additives and effect on morphology of electrodeposits (Schwartz) • Patterns in electrodeposits (Dobrovolska): “electrochemical Belousov–Zhabotinsky reactions” in silver alloy deposition.
F5: Semiconductors, Metal Oxides • Rajeshwar: electrodeposition of semiconductors – review • Growth of II-VI, plus TiO2, p-Cu2O • Others: • Josell: CdTe on interdigitated electrodes • Ribeaucort (Lincot): CIGSe • Izaki: p-Cu2O (Eg ca. 2.0 eV) • TiO2/Au nanoparticles composite. Interesting because TiO2 by electrodeposition. • Electrodeposited Fe2O3 and TiO2/WO3 composite • Fe2O3 by electrochemically initiated precipitation
B9: Semiconductor-Electrolyte Interfaces • Major focus:- DSSCs. Characterisation, modelling etc. • Impedance and IMPS methods (NB a commercial IMPS system is now on the market) Hydrogen production • Photoelectrochemistry of Fe2O3: • SD: two significant questions: do I need to invoke surface states to model the material performance? Presence of oxygen? • Heli Wang (NREL): nanorod Fe2O3 (not their own, but good performance), application in a photoelectrochemical diode. • Other: • PV assisted photoelectrolysis with C-TiO2 (Khan); WO3-Fe2O3 “heterojunction”; (In,Ga)N.
