The paper shows that high–quality super-conducting Nb films can be deposited by means of arc discharges under ultra–high vacuum conditions. The critical temperature Tc of Nb–films obtained with a planar cathodic arc Ultra High Vacuum (UHV) system, is very close to that of pure bulk niobium Tc = 9.26 K and the transition to super–conducting state is very narrow. The films have higher Residual Re...
The role of the cantilever in quantitative Kelvin probe force microscopy (KPFM) is rigorously analyzed. We use the boundary element method to calculate the point spread function of the measuring probe: Tip and cantilever. The calculations show that the cantilever has a very strong effect on the absolute value of the measured contact potential difference even under ultra-high vacuum conditions, ...
Located far from anthropical disturbances and with low seismic magnetic background noise profiles, the LSBB facility is ideal location for a new hybrid detector study of space-time strain. The MIGA infrastructure [1], utilizes an array atom interferometers manipulated by same beam, resonant optical field 150 m long cavity. constitutes method geophysics, characterization spatial temporal variati...
