Turning down the heat on semiconductor growth: Solution‐chemical syntheses and the solution‐liquid‐solid mechanism

Abstract

Semiconductor crystal growth at low temperatures and under mild reaction conditions would usher in a technological revolution. Following a brief discussion of the processes that occur during crystal growth, several growth techniques are described, including electrodeposition and surfactant‐interface growth. Particular attention is paid to solution–liquid–solid growth, a technique discovered by the authors that resembles a living polymerization and a phase transfer reaction, by which crystalline III—V materials are produced at the lowest known growth temperatures.

Synthesis and characterization of silver molybdate nanowires, nanorods and multipods

“…Various methods have been developed to synthesize 1-D nanomaterials (Klein et al 1993;Dai et al 1995;Morales and Lieber 1998;Pan et al 2001). In contrast, the solution approaches have been proved to provide an alternative route for the synthesis of 1-D nanomaterials (Buhro et al 1996;Holmes et al 2000;Peng et al 2000;Peng 2001, 2002). The template method is known to be a very effective method for the fabrication of the desired materials (Torigoe and Esumi 1995;Nagappa et al 2005).…”

Tungstate/titanate composite nanorod as an efficient visible light photo catalyst

“…Generally, one dimensional nanostructures can be fabricated by template directed growth methods such as using carbon nanotubes [11,12], porous aluminum templates [13,14], the vapor liquid solid (VLS) [15][16][17] and the vapor solid (VS) mechanisms [18]. Solution approaches have also been explored for the synthesis of one dimensional nanostructures [8,[19][20][21][22]. Previous work has shown that the solvothermal/hydrothermal process is a versatile route for the synthesis of various semiconductors nanorods [23], lanthanide hydroxide nanorods [24] and thin tellurium nanobelts/tubes [25].…”

Synthesis of Semiconducting Functional Materials in Solution: From II‐VI Semiconductor to Inorganic–Organic Hybrid Semiconductor Nanomaterials

“…), and the reaction was usually initiated under mild conditions or under natural conditions to turn down the heat for the synthesis of materials. [68,69] Recent advances in soft synthesis of diverse nanomaterials have demonstrated that soft approaches are indeed promising for controllable synthesis of low dimensional nanostructures such as one-dimensional (1D) nanostructures of chalcogens and chalcogenides, [70] and inorganic nanotubes. [71] In this Feature Article, we highlight the latest development and emerging new synthesis solution strategies for the syntheses of II-VI semiconducting nanomaterials and inorganic-organic hybrids semiconductor materials.…”
