The Magnetic Field

AbstractBilayer microbridges of aluminum and hydrogenated amorphous silicon are fabricated using thin film technology and surface micromachining at low temperatures on glass substrates. The microstructure is electrostatically actuated by applying a voltage between the bridge and a metal gate counter electrode placed beneath it. The movement is measured with a precision close to 0.1 Å by sensing the magnetic field of a permanent magnet, deposited and patterned on top of the microbridge, with an integrated spin valve magnetic sensor. The deflection of the bridge is at the same time monitored using an optical setup. The deflection of the structures is studied as a function of the driving applied gate voltage and bridge length and experimental results are analyzed with an electromechanical model.

ABSTRACTIn the present communication, we report our efforts to integrate chalcogenide-based photoelectrochemical (PEC) materials into a standalone device capable of water-splitting using sunlight as the only source of energy. More specifically, the PEC performances of copper gallium diselenide are presented. First, a brief introduction to the material microstructural characteristics is presented. Then, the PEC properties are discussed, including incident-photonto-current efficiency (>60% in the visible), Faradaic efficiency (uncatalyzed, 86%) and durability (400 hours). Finally, we report the solar-to-hydrogen benchmark efficiency (3.7%) of a device made of a CuGaSe2 photocathode and a-Si solar cells measured in a 2-electrode configuration using a RuO2 counter electrode.
