FIG. 1.

Optical transmission of a 150-nm yttrium film capped with 5-nm Ni (sketched in the inset) during loading. The film is exposed to 2-bar hydrogen at 423 K at . For the transmission lies in the noise level of the camera.

Arrhenius plot of the reciprocal switching time and the slope determined from temperature-dependent transmission measurements similar to that in Fig. 1.

Left: Chemical shift of the Ni LVV Auger line with respect to the KLL line as a function of the location on a gradient sample. The proposed structure of the clusters is sketched. Right: Transmission of the corresponding sample (5-nm on 150-nm surface oxidized yttrium) during hydrogen exposure at 2 bar, 403 K, as a function of location and time. Bright intensities display high transmission. Two representative linescans at fixed positions (, ) and a linescan at fixed time are given for illustration.
