Effect of deposition voltage on the field emission properties of electrodeposited diamond-like carbon films

Electrical characterization of metal/diamond-like carbon/inorganic semiconductor MIS Schottky barrier diodes

“…1a shows Raman spectrum of the DLC film. Raman spectra exhibited two strong and sharp peaks at 1330 cm −1 (D peak) and 1590 cm −1 (G peak), being in agreement with spectral characteristic of DLC films [3,14].…”

“…In contrast, electrodeposition method is much easy and has advantages such as availability for large area deposition, low deposition temperature, low cost and simple equipments. As the properties of DLC films highly depend on deposition methods and conditions [14], the obtained results would be different from the other methods. According to our best knowledge, there is no study on metal/DLC/Si MIS devices in which DLC films were deposited by electrochemical method.…”

“…These materials have been used in many electronic applications such as microelectronic-mechanical systems, low-k dielectric films in integrated circuits, solar cells, displays, strain gauges, cold cathode field emitters, metal semiconductor metal structures, a-C/c-Si heterostructures and thin film transistors [1,3,[9][10][11][12][13][14][15][16].…”

Electron field emission of iron and cobalt‐doped DLC films fabricated by electrochemical deposition

“…However, some inherent limitations, such as low total field emission current, high level of residual stress and weak adhesive strength of DLC films, restricted the optimum field emission performance and service stability to some extent, as well as its potential applications . Many investigations confirmed that the incorporation of heteroatoms (including metal and nonmetal) in the carbonaceous network has been proposed as an alternative way not only to lower the intrinsic stress and improve the mechanical behaviors but also to improve the FEE properties of DLC films . Especially, great interests arose from the experimental and theoretical researches on metal elements doping into DLC films for several reasons.…”

Deposição de estruturas carboniferas por processo eletroquimico atraves de solução organica em temperatura ambiente

“…R.S. Li et al[47] relatam que aumentando o potencial aplicado, a posição do pico G desloca-se para número de ondas menores (cm -1 ), bem como a razão os autores, isto indica uma redução no conteúdo de ligações tipo sp 2 devido ao aumento do potencial.Em resumo: Realizando uma comparação entre os valores da razão de intensidade 3.3 e 3.6 pode-se afirmar através dos estudos realizados para DLC que os resultados contidos na tabela 3.6 (com eletrólito de etanol mais água deionizada) possuem maior concentração de ligações tipo sp3 , tendo um DLC de melhor qualidade. As estruturas (DLC e diamante) obtidas em baixas temperaturas são de boa qualidade.…”
