“…For the synthesis of inorganic particles, the most common method is based on the solution phase. This method has been used to synthesize nanoparticles of II-VI compounds (e.g., CdS, PbS), 10,11 III-V compounds (GaAs) 12 and a wide range of metal oxides including TiO 2 , 13 ZnO, 14 Fe 2 O 3 , 15 and PbO, 16 Fe 3 O 4 . 17 Nano-ZnO, as one of the multifunctional inorganic nanoparticles, has drawn increasing attention in recent years due to its many signicant physical and chemical properties, such as chemical stability, 18 low dielectric constant, 19 high transmittance, 20 high catalysis activity, 21,22 effective antibacterial and bactericidal action, 23,24 UV-screening 25,26 and infrared absorption.…”

This work presents a facile approach to synthesize P(VC-co-AAEM) (vinyl chloride copolymerized acetoacetoxyethyl methacrylate)/zinc oxide (ZnO) nanocomposite particles with raspberry-like shape by a nano-coating technique. It is proved that the interactions between the b-diketone groups embedded in AAEM and ZnO precursors are crucial to forming the raspberry-like morphology, as such, the content of AAEM has a significant effect on the nucleation and growth of ZnO nanocrystals on the P(VC-co-AAEM) beads. SEM analysis demonstrated that ZnO nanocrystals were deposited on the surface of template nanoparticles as small clusters with different sizes and quantity, depending on the reaction parameters. X-ray diffraction of the P(VC-co-AAEM)/ZnO nanocomposite particles revealed that the addition of functionalized PVC beads lowered the formation of ZnO nanocrystals due to the constraining effect of the ZnO-AAEM interaction on the mobility of ZnO precursors. Additionally, such PVC/ZnO composite particles were found to have excellent foamability of nanometer-sized pores, which could have various potential applications in sound insulation and thermal insulation.

“…Current controlled liquid phase epitaxy (CCLPE) is a cost effective technique to achieve a thick epilayer without any adverse environmental affects [23,24]. Growth mechanism of GaAs in CCLPE has been investigated theoretically and experimentally on the flat substrate and it is concluded that electromigration of solute dominants the growth with higher thickness at the center of the epilayer than its periphery [25][26][27][28]. The preliminary studies about selective epitaxial growth of GaAs on circularly patterned GaAs substrate by CCLPE showed higher growth at periphery than its centre and it motivated to study the selective epitaxial growth in detail.…”

“…The total driving force is the sum of these two effects. The growth mechanism in CCLPE was investigated theoretically and experimentally, and it was concluded that electromigration dominates the growth mechanism in III-V compound semiconductor growth [24][25][26][27][28][29][30].…”

a b s t r a c tSelective epitaxial growth of a GaAs layer on SiN x masked Si-doped semi-insulating (1 0 0) GaAs substrate was performed by current-controlled liquid-phase epitaxy (CCLPE) in the conventional liquidphase epitaxy. Experiments were carried out with and without the application of electric current. Surface morphology of (1 0 0) facet of the grown layer and the vertical and lateral growth rates were significantly improved under applied electric current. A thick layer of about 330 mm was achieved at relatively low growth time of 6 h with a current density of 20 Acm À2 . The epitaxial growth is realized by both electromigration of the solute and supercooling under a constant rate of furnace cooling. The dislocation density of the grown layer was significantly reduced, compared with that of the substrate (4 Â 10 4 cm 2 ).
