Probing molecular orientation of donors and acceptors in all-polymer blend films by near-edge x-ray absorption fine structure spectroscopy
The molecular orientation is crucial for the efficiency of organic solar cells. A face-on orientation, in which the $\pi - \pi $ stacking direction is oriented perpendicular to the substrate, is typically preferred because it enhances vertical charge transport to the electrodes and can additionally…

Growth of c-axis AlN sputtered films on silicon-based substrates using 2D-TMD as nucleation layer
In RF filters based on bulk acoustic wave (BAW) resonators, AlN is a well-known piezo-active layer stacked between two molybdenum electrodes. The crystalline quality, e.g., the film texture along the c -axis of the AlN hexagonal lattice, has a direct effect on RF performances. However, the current…
