RESUMO

This thesis presents a study of the growth and characterization of nano crystalline diamonds produced by the hot-filament chemical vapor deposition (CVD) with the introduction of boron during the growth process. Our objective was to produce samples with good electrical properties for field induced emission of electrons (FEE) to the vacuum. Characterization of the samples by electron microscopy, Raman micro-spectroscopy, and Field Emission measurements are presented and discussed
