The increase in LRR with increasing stiffness of the encapsulating layer is attributed to the increase in thermal stress in the encapsulation dielectric stack layer and in the metal lines due to their increased constraint.
Meanwhile, the encapsulating layer protects the nanocavity structure from deformation at high temperatures.
To get access to the metal contact to p-GaN shells, which is between the 18-μm PDMS encapsulating layer and the 0.5-mm cap layer, the cap layer was mechanically released over a small area at the sample edge and a piece of aluminium foil was attached to the metallization with silver paint, as schematized in Fig. 3b.
Compared with inorganic coating, the high polarity and outstanding film forming capability of organic coating, plus its strong affinity to transitional inorganic materials surfaces, might contribute to a facile formation of a nanometer-thick and highly continuous encapsulating layer on the surface of active materials.
The high polarity and outstanding film forming capability of PAA, plus its strong affinity to transitional inorganic materials surfaces, might contribute to a facile formation of a nanometer thick, highly continuous, and ionic-conductive PI encapsulating layer on the surface of active materials [124].
For microneedles encapsulating layered PLGA implants, sequential microparticle deposition, drying, and melting was performed as previously described.
We obtained hydrogel-magnetic nanoparticles with a magnetic core (Fe3O4) encapsulated in layer-by-layer chitosan hyaluronic acid hydrogel.
Subsequently the metal particles are encapsulated in layers of graphitic carbon by exposure to methane at 700°C.
The role of carbon-encapsulating layers is to isolate the metal nanoparticles from each other, thus avoiding the problems caused by interactions among closely compacted magnetic units.
We report on controlled band gap modification in a compressively strained InGaAsP multi-quantum well-laser structure using different encapsulating layers followed by rapid thermal processing (RTP).
The characterization of the spent samples by transmission electron microscopy (TEM) revealed the presence of carbon deposits of different nature in the Mg/Al samples having a high MgO content, including filamentous carbon (whiskers), onion-shell like sheets and/or amorphous encapsulating layers.
