A Photoelectrochemical Study of the GdMg Hydride Switchable Mirror

Abstract: A significant chemical stability has allowed us to perform photoelectrochemical measurements on the semiconducting state of the GdMg hydride system. With electrical impedance spectroscopy we confirm that GdMg hydride in the transparent state is an n-type semiconductor. The donor density was estimated to be 5 ϫ 10 21 cm Ϫ3. Impedance measurements give information about the potential distribution at the semiconductor/solution interface. Photocurrent was observed in the transparent state. It is proposed that phot… Show more

According to the pressureconcentration isotherm of vanadium hydride 22 ences the electronic properties of vanadium, which in turn mediates the exchange coupling between the iron nanocluster aggregates. Consequently, the effect of hydrogen absorption on the magnetic properties explains the change in Kerr rotation.…”

“…The active film covered only part of the ITO surface to allow a back contact to the film via the ITO. 12 To ensure good adhesion of the gadolinium, a 0.5 nm thick magnesium layer was evaporated onto the ITO. The layers were deposited by evaporation at 10 Ϫ7 mbar base pressure.…”
