First Nano offers access to our Application Lab for growing nanowires where Nano/Solar/Energy material processes can be developed in conjunction with First Nano/CVD research scientists. Please contact us for more information.

High quality ZnO nanowires can be deposited either vertically aligned or randomly oriented on Si and Sapphire substrates. With the unique solid source vapor generator design, ZnO nanowires with a uniform length and diameter can be deposited on the whole 2" wafer. The same method can be applied to other oxides and nitride nanowire growth. These nanowires are used for applications such as optoelectronic and Piezoelectric.

GaN Nanowires

(Image 3 on right) GaN are produced by using a solid source precursor which provides high quality and reproducible nanowires for use as optoelectronic devices.
