Alternative to carbon nanotubes
Researchers at the Georgia Institute of Technology have found that with a combination of aluminum oxide, silicon and germanium, it is possible to obtain a material from which nanotubes are cheaper to make than carbon ones. In addition, the properties of nanotubes from such materials are easier to control.
The production of semiconductors and carbon nanotubes occurs at high temperatures and pressures, forcing chip manufacturers to experiment with doped organic polymers. But organic polymers in their properties are significantly inferior to inorganic metal oxides. According to the researchers, nanotubes made of aluminum oxide, silicon and germanium combine both the simplicity of polymer production (the formation of such nanotubes occurs at normal pressure and temperature below 10 ° C degrees Celsius) and high rates of inorganic materials.
