Boron-based coatings can be very useful in neutrons detection application.

Ti interlayer is likely to decrease the internal stress at the substrate-film interface, thus smoothing the difference in lattice parameters between the growing film and substrate.

Abstract
Boron-based coatings can be very useful in neutrons detection application. Here, stable boron carbon (B-C) films in nanometer scale were deposited on silicon substrates with titanium interlayer by RF plasma magnetron sputtering. Ti interlayer is likely to decrease the internal stress at the substrate-film interface, thus smoothing the difference in lattice parameters between the growing film and substrate. The B-C/Ti/Si coatings were characterized using SEM, EDS, AFM and XRD. The enhancement in adhesion of the B-C film to the substrate was analyzed by a scratch tester measurements.File in questo prodotto:
