Therefore, when Sn[O.sub.2] is doped
with Sb, Sr, Ga, Ti, and Ge, the bandgap between the valence band and the conduction band is different; that is, the bandgap values are different.
Preparation of highly efficient Al doped
ZnO photocatalyst by combustion synthesis.
Although a doped
athlete performs better, he will not benefit from this performance improvement.
In this results, more adsorption efficiency in nickel doped
Ti[O.sub.2] compared with synthesis Ti[O.sub.2].
Figure 1(b) shows the X-ray diffraction patterns of the Ni doped
Sn[O.sub.2] powder samples in the diffraction angles (2[theta]) between 26[degrees] and 27[degrees].
As for analysis from Figures 2(a) and 2(b), with Cu, In doped
, the absorption spectra of the samples regardless of Cu-doped-CdS/In-doped-CdS (394 nm) or In-doped-CdS/ Cu-doped-CdS (377 nm) began to move towards the long wavelength compared with undoped CdS (364 nm) sensitized Ti[O.sub.2] photoanode.
The J-V characteristics of those QDSSCs samples based on diverse doped
ratio are presented in Figure 3, with 4 cycles of SILAR.
Furthermore, ZnO thin film doped
with 2 at.% Sn shows the highest current intensity among all of the Sn-doped ZnO thin films, reflecting the best optimal electrical properties.
Hence, since the doped
athlete is part of a network around him, the sports world is in need of the state's assistance.
with d,l-camphor sulfonic acid and processed from m-cresol solution is one notable exception .
Hebard of AT&T Bell Laboratories in Murray Hill, N.J., surprised scientists at the meeting with evidence that [C.sub.60] films "doped
" with potassium become superconductors when chilled to 18 kelvins -- a much higher temperature than he and his colleagues expected, he says.
Usually polyacetylene semiconductors, like traditional semiconductors, need to be "doped
" with impurities in order to conduct electricity.
