... optimized amount of 1,8-octanedithiol can be determined. As the amount of 1,8-octanedithiol was increased, the i ntensity of the UV-Vis absorption and the crystallinity of P3HT significantly increased, and the ... layer, the J-V characteristics of the active layer were improved, and consequently, higher power conversion efficiency [PCE] of the device was obtained...

... The effect of Mn concentration Other than the variation of the MnGe and Ge layer thicknesses, the change of Mn concentration can also be employed to control the behaviors of grown MnGe nanostructures. ... and growth temperature on the structure of the GeMn/Ge superlattices grown by MBE. We found that by varying the growth parameters, the structure of...

For the estimation of the island volume, we considered only the portion of the dome above the sur- rounding 2D flat surface; the contribution of Ge volume inside the pit underneath the island ... accompanied by a plastic relaxation by misfit dislocations. The experimental verifi- cation of these hypothesis overcomes the scope of the present paper, but...
