Improvement on electrical conductivity and electron field emission properties of Au-ion implanted ultrananocrystalline diamond films by using Au-Si eutectic substrates Hasselt University
In the present work, Au-Si eutectic layer was used to enhance the electrical conductivity/electron field emission (EFE) properties of Au-ion implanted ultrananocrystalline diamond (Au-UNCD) films grown on Si substrates. The electrical conductivity was improved to a value of 230 (Omega cm)(-1), and the EFE properties was enhanced reporting a low turn-on field of 2.1 V/mu m with high EFE current density of 5.3 mA/cm(2) (at an applied field of 4.9 ...
