New nanocluster to boost thin films for semiconductors
Date:10/31/2008

Oregon researchers have synthesized an elusive metal-hydroxide compound in sufficient and rapidly produced yields, potentially paving the way for improved precursor inks that could boost semiconductor capabilities for large-area applications.

The key to a "bottom-up" production of possibly the first heterometallic gallium-indium hydroxide nanocluster was the substitution of nitroso-butylamine as an additive in place of nitrosobenzene.

The substitute was identified during a comprehensive screening of potential alternatives by Zachary L. Mensinger, a doctoral student in the lab of University of Oregon chemist Darren W. Johnson. The additive acts to optimize and speed crystallization, allowing for reaction yields up to 95 percent. Comparable compounds traditionally made under caustic conditions often take months or even years to crystallize and result in low yields.

"The benefit is that we can predictably control the ratio of gallium and indium in these structures at molecular levels, which can result in the same control in the fabrication of semiconductor thin films," Johnson said. "We can tailor the properties for specific applications or for different performance levels."

Six University of Oregon and Oregon State University collaborators, working under the umbrella of the Oregon Nanoscience and Microtechnologies Institute (ONAMI), a state signature research center, describe their findings a paper to appear in the German Chemical Society's journal Angewandte Chemie (Applied Chemistry) International. The research, published early online, also was performed under the auspices of a new National Science Foundation-funded Center for Green Materials Chemistry, operated jointly by the two Oregon universities.

"Researchers working in the solid-state materials community are looking at these kinds of nanoclusters as precursors for thin films and other advanced materials, but you typically cannot get them in high enough
