Fabrication of highly ordered nanocrystalline Si:H nanodots for the application of nanodevice arrays

Metal–organic framework based mixed matrix membranes: a solution for highly efficient CO2capture?

“…Particle morphology is crucial for many applications and allows the properties of a certain solid to be tuned without changing the material composition. For instance, the improved performance of gold or silver nanoparticles for surface plasmon resonance, 217 semi-conductor nanodots for quantum confinement, 218 and metal or metal oxides for catalysis 219,220 is strongly dependent on crystal morphology. In case of MMMs, it is easy to envisage that the performance of membranes containing exactly the same material but with a different particle configuration will result in different separation performance.…”

Morphology Design of Porous Coordination Polymer Crystals by Coordination Modulation

“…On account of the relevance and beauty of biomineralizations and snow crystals, particular emphasis has recently been placed on the control of crystal morphology, because in many cases it allows the properties to be tuned without changing the material composition. For instance, the improvement of capabilities of gold or silver nanoparticles for surface plasmon resonance, semiconductor nanodots for the quantum confinement effect, and metal or metal oxides for catalytic activity is strongly dependent on crystal morphology. In the case of porous materials such as zeolites, the crystal morphology or the facet exposed to the external surface is of significance for their catalytic activity, because the reaction not only requires diffusion but also the availability of active sites that are embedded into the framework scaffold …”

Directional growth of nanocrystalline Si nanorod array by mid-frequency magnetron sputtering

“…Due to the shadowing masks, these arrays possessed more uniform size and spacing than those of the Si nanorod arrays in our experiments. Moreover, Ding et al have fabricated highly ordered nanocrystalline Si:H nanodots on Si substrates by combining plasma‐enhanced CVD with an alumina template‐based fabrication approach. However, it is difficult to prepare Si nanorod arrays through the above template approach because of the high‐aspect‐ratio of the nanopores in the alumina membrane mask.…”
