3.6 p3ht/zno interface: high deposition rate 41Figure 3.11.: 100 HDR system before (left) and after (right) the relaxationat low temperature.At room temperature the 100 HDR interface (Figure 3.13)shows a partially restore of the crystalline order that can beobserved in all directions (Figure 3.12 bottom panels). Wecan further recognize the zigzag-like conformation alreadyobserved for P3HT bulks in section 2.2.The two HDR interface models have been compared interms of interface energy (the energy of the hybrid interfacewith respect to separate components divided by thearea of the interface) and binding energy. Despite the surfaceformation energy of the 010 surface is higher thanthat of the 010 one (by 0.008 J/m 2 ), its higher binding energywith the ZnO with respect to the 100 case (by 0.1J/m 2 ), bring to a favourable formation of 010/ZnO interfaceswith respect to the 100/ZnO systems. This is consistentwith the preferential face-on orientation of polymer

In conclusion, present results showsthat the 010/ZnO surface is the most likely to occur inP3HT/ZnO systems.In order to better connect present analysis to experimentaldata we average the structure factor in the interfaceplane (xy) by calculating the S xy quantity. S xy recalls theGrazing Incident X-ray Diffraction (GIXD) measurementwhere X rays are diffracted by scattering parallel to the interface.For the 010 HDR interface, the peaks of the polymerbackbone and that of the interdigitation periodicity are stillwell recognizable in S xy curve ( right panel of Figure 3.14).
