The base diameter is around four times larger than the tip diameter, and the NWs therefore display a clear conical morphology (Fig 7b).
Higher growth temperature also improves Al migration and then increases the amount of Al adatoms that migrate to the top of NWs; therefore, the axial growth rate of NWs increases [13].
Effect of Ag clusters in 3SZO, 5SZO NWs decreases resistances because of Ag clusters of high electric conductivity, as shown in Figure 3. Also, Ag clusters act defect in 3SZO, 5SZO NWs; therefore, both 3SZO and 5SZO NWs have a high E a than 1SZO NWs.
PE resulted in higher demands and longer duration of UE motion than NW, and therefore may be the preferred tool when UE ROM or muscular endurance are the goals of rehabilitation.
In this case, the impedance match plays an important role in coupling the incident light into the NW cavity; therefore, the front-opening crescent configuration has the born benefit in enhancing the absorption performance of SNSCs as displayed in Fig. 2c2.
For general condition, the spontaneous reaction is loath to reveal in the ZnO NWs application; therefore, we have suppressed the spontaneous reaction from our c-ZnO NWs devices by using surface oxygen/hydrogen plasma treatment [30].
The longest diffusion length found for the case of <110>-oriented Ge NWs is, therefore, consistent with atomically flat {111} sidewalls in comparison with the rough-facetted {112} sidewalls of the <111>-oriented NWs.
ZnO NWs have therefore emerged as promising building blocks for nanostructured solar cells such as dye- and quantum dot-sensitized solar cells as well as extremely thin absorber solar cells, all of them including the type-II band alignment[10 13].
Therefore, NW arrays were studied with a fixed NW bottom diameter of 100 nm while the top diameter was varied from 0 nm (ideal sharp tip) to 100 nm (cylindrical NW).
Therefore, the NW density will decrease with increasing growth temperature.
