| dc.description | This study investigated the production of boron films by femtosecond pulsed laser deposition (PLD) to be used as converters
on bulk semiconductor neutron detectors. The ablation threshold of metallic boron was determined and the film growth was
studied as a function of deposition time (5???90 min) and laser pulse energy (35???530 ??J). The films were characterized by
scanning electron microscopy (SEM), revealing a flaky morphology, optical profilometry, which determined the films thicknesses
(from 80 nm up to 4 ??m), Ion Beam Analysis (IBA) that assessed their elemental composition and X-ray diffraction
(XRD), which revealed an amorphous structure. In addition, a thermal load study was performed to evaluate the heat flux
onto the substrate during deposition process. Stable boron films obtained show that the femtosecond PLD process is reliable
and reproducible for the fabrication of thick boron coatings. | |
