	abstract = {Boron carbides (BxC1−x) in thin film form have been synthesized in a high vacuum by coevaporation of B and C atoms from independent sources, allowing a study of the whole composition range from pure B films to pure C films. The relationship between the impinging B∕C atomic fluxes and the film composition has been studied, providing information on the chemical reactivity between the B and C vapors. The composition was determined with x-ray emission energy dispersion spectroscopy and x-ray absorption near edge spectroscopy (XANES). Finally, the bonding structure of the films has been determined by XANES, showing a change from structures based on B12-icosahedral units for the B-rich samples to hexagonal-like structures for the C-rich samples. The study shows that the structural transition takes place for x∼0.5.},
