Ordered MgB2 thin films have been successfully grown on Mg(0001) by molecular beam epitaxy (MBE). By simply depositing B on the Mg substrate a maximum film thickness of about 4 ML can be achieved, while thicker layers can be obtained by co-deposition or alternated deposition of Mg and B. Thick films show hexagonal low energy electron diffraction patterns and the photoemission and x-ray absorption features typical of MgB2.

Abstract
Ordered MgB2 thin films have been successfully grown on Mg(0001) by molecular beam epitaxy (MBE). By simply depositing B on the Mg substrate a maximum film thickness of about 4 ML can be achieved, while thicker layers can be obtained by co-deposition or alternated deposition of Mg and B. Thick films show hexagonal low energy electron diffraction patterns and the photoemission and x-ray absorption features typical of MgB2.File in questo prodotto:
