These dielectric materials have been designed to provide other benefits, such as acting as a passivation layer to prevent harmful recombination effects, a diffusion barrier to prevent unwanted diffusion of dopants into certain regions, and a masking material.
The researchers are able to fabricate transistors whose channel dopants are introduced one-by-one, revealing that channel dopant location has a strong impact on sub-threshold current variability.
Using a combination of dopants is a simple method to improve the processability of ICPs while retaining useful levels of conductivity.
The point-of-use Maxi Gaskleen purifier with SIP material was evaluated by CVD Equipment Corporation and was found to lower dopant metal contaminants (As, P, Al and B) in a low grade silane line, resulting in improved silicon-epitaxial layers with impurities in the parts per trillion atomic (ppta) range," said Karlheinz Strobl, VP of business development, CVD Equipment Corporation.
Earlier work showed that the data could be varied over a very wide range in a systematic fashion and correlated with the densities of the incorporated dopants.
4] doped polyaniline may be due to some chemical reaction of the dopant ion with the polymer chains and also morphological changes at higher temperatures since HCl[O.
The FASTC2D computer software transforms pixel data from an SCM image into a map that accurately shows the distribution of dopant atoms.
Chen and his colleagues at Rowland and the Chinese Academy of Sciences in Beijing, however, report a step toward finer dopant control.
The key was determining the right reactor conditions to deliver the dopants to the silicon, he found.
They cover the electrochemistry and photoeloctrolysis of hydrogen generation; photocatalyic reactions, oxidation, and reduction; transition metal oxides; crystal structure and electronic structure; optical properties and light absorption; impurity, dopants, and defects; surface and morphology; and soft X-ray spectroscopy and electronic structure.
Using various combinations of these dopants and hosts, Novaled can optimize OLED performance for lifetime or efficiency, depending on application requirements.
Unfortunately, doping with these cations decreased the capacity because the valences of dopants are usually less than four, which decreases the amount of [Mn.
