专利号:US-11332368-B1 优先权日:2019-12-28 标 题:Methods for high-yield synthesis of higher germanes and higher silanes 发明人:HUANG BAOQUAN; LEE HENRY 权利人:GE SOLARTECH LLC 摘要:High-yield synthesis of higher germanes and higher silanes includes the hydrolysis of a germanium- or silicon-containing alloy with chemical formula AxByGe(Si), wherein A=Mg, Ca, Sr, Ba, Li, Na, K, Rb, Cs, and rare earth metals; B=Al, Si, Sn, Ga, Zn, Fe, Co, Ni, Cu, Ag; x=0-10, y=0-10. The hydrolysis reaction is promoted by an acidic substance such as boron oxide (B2O3), citric acid, hydrochloric acid (HCl), or sulfuric acid (H2SO4). The present invention provides an efficient method of drying higher germanes and higher silanes to prevent their further hydrolysis. Another synthetic process involves the reaction of germanium oxide, borohydride and boron oxide with water. Still another process comprises hydrolyzing the Si1-xGex alloy with a very dilute base solution. The methods enable production of higher germanes from a wide range of germanium-starting materials, including germanium byproducts, impure germanium compounds, and waste products generated in the plasma deposition of thin films containing germanium.

专利号:US-8138067-B2 优先权日:2009-06-12 标 题:Method and system for the synthesis of semiconductor nanowires 发明人:RYAN KEVIN M; BARRETT CHRISTOPHER 权利人:RYAN KEVIN M; BARRETT CHRISTOPHER; UNIV LIMERICK 摘要:The invention provides a system and method for producing semiconductor nanowires, for example germanium or Silicon, grown by solution decomposition comprising the steps of heating at least one high boiling point solvent to its reaction temperature in a chamber and injecting a precursor directly into the chamber to react with the at least one high boiling solvent to produce a refluxing solvent. Subsequent vapour deposition of a monomer, achieved by the refluxing solvent, onto a locally heated substrate contained within the chamber produces the semiconductor nanowires. The system and method removes the dependency upon the incorporation of metal catalyst for the production of silicon and germanium nanowire, thereby nullifying the adverse effects of metal contamination in the resulting semiconductor nanowires.
