TL;DR: In this paper, the performance of solar cells with stacked self-assembled Ge dots in the intrinsic region of Si-based p-i-n diode was investigated and the results showed that electron-hole pairs generated in Ge dots can be efficiently separated by the internal electric field, and can contribute to the photocurrent without considerable recombination in Ge/Si interfaces.

TL;DR: In this article, the grain growth behaviors of polycrystalline silicon during directional growth from melt were investigated using an in situ monitoring system, and the authors suggested that the undercooling at the growth front is the key parameter to divide those growth behaviors.

TL;DR: In this article, the surface micro-topography of tetragonal lysozyme crystals was observed in situ by laser confocal microscopy combined with differential interference contrast microscopy (DIM).

TL;DR: The interaction energy calculated including DLVO and non-DLVO factors shows that a lipid membrane on the TiO 2(100) gains 20 times more energy than on SiO 2, which makes the fluid SPLB precisely follow the substrate structure of angstrom order.

TL;DR: In this article, columnar domains with different sizes were observed in the as-grown sputtered AlN films, and they were shown to split into irregularly shaped and coalesced at an elevated annealing temperature, resulting in improved crystal quality.
