SEM investigations of the samples revealed that increasing dopant concentration of V increased the grain size little .
The insertion and variation of the rare earth dopants concentration has possibilited the formation of new structures as well as the change on the morphology from nanorods (for pure ZnW[O.sub.4] crystals) to nanospheres (for RE doped ZnW[O.sub.4] crystals).
The binary dopant system was prepared by dissolving SDS in 1 M aqueous HCl solution to a concentration of 5 mM.
Uneven NiSi/Si interface [14] and random dopant fluctuation (RDF) [15, 16] can also fluctuate the contact resistivity and thus induce the DC performance variations.
On the surface, the second most exposed oxygen atom was replaced by the dopants (see Figure 1(b)).
These thinfilms have been fabricated using precursor solution prepared with dopant concentration 0.01 mol %, coated at spin rate 3500 rpm and heat treated at 350 [degrees]C.
The absorption bands of PEDOT can also be seen in the hybrid nanocomposite upon the addition of dopants into PEDOT indicating that the dopants and PEDOT were successfully incorporated together.
In this section we present a simulation case in which we use SCM to obtain the locations of the dopants in a 2-D semiconductor.
Among the various dopants lanthanum substitution is the most important as its ionic radius matches well with bismuth [7, 9].
With the continual pressure of keeping up with new dopants, and anticipating the next trends in doping practices, it may now be prudent to create a coordinated approach to face these challenges.
Additionally, the release of dopants from PPy backbone resulted in the passivation in the defect areas improving the corrosion protection ability.
