From micro to nanocrystalline transition in the diamond formation on porous pure titanium

Diamante dopado com boro obtido pela técnica HFcVD para detecção eletroanalítica de metai

“…Outro problema referente ao crescimento de filmes DDB relaciona-se com a formação de fases intermediárias como hidreto e carbeto de titânio. Estes fatores, em conjunto, fragilizam as amostras e podem ser responsáveis pela formação das referidas rachaduras e delaminações nos filmes DDB (22,25) . Portanto, o crescimento de filmes de diamante sobre substratos de titânio com boa qualidade é um grande desafio, o qual foi vencido neste trabalho através do ajuste dos parâmetros experimentais.…”

The synthesis of diamond films on adamantane-coated Si substrate at low temperature

“…The exceptional physical and chemical properties of diamond such as wide band gap, chemical inertness, high carrier mobility, excellent biological compatibility, high propagation speed of acoustic wave, good optical transparency, high thermal conductivity and the greatest hardness that make its use advantageous in a wide range of applications [5][6][7]. Several methods have been proposed for the synthesis of high crystalline diamond films by microwave plasma chemical vapor deposition (MPCVD) at high temperature and pressure [7][8][9][10][11][12][13]. However, to make commercially viable further investigations are still required in terms of yield, quality and uniformity of diamond.…”

Influence of Supporting Electrolytes on RO 16 Dye Electrochemical Oxidation Using Boron Doped Diamond Electrodes

“…The second is associated to the formation of intermediate phases such as hydride and titanium carbide. These factors together weaken the samples and they are responsible for the formation of cracks and delamination in diamond film 24 . increasing the doping level this band increases significantly and a drastic reduction in the diamond peak is observed.…”
