This etching template may comprise an anodized metal oxide, such as an anodized aluminum oxide (AAO) thin film. The substrate insulating layer is then selectively etched to define a second array of nano-channels therein. This selective etching step preferably uses the etching template as an etching mask to transfer the first array of nano-channels to the underlying substrate insulating layer, which may be thinner than the etching template. An array of semiconductor nano-pillars is then formed in the second array of nano-channels. The semiconductor nano-pillars in the array may have an average diameter in a range between about 8 nm and about 50 nm.Type: GrantFiled: January 20, 2004Date of Patent: July 5, 2005Assignee: North Carolina State UniversityInventors: Zhibo Zhang, Veena Misra, Salah M.

Patent number: RE40788Abstract: A litho strip for use as an offset printing plate is described which has a composition of 0.05-0.25% Si, 0.30-0.40% Fe, 0.10-0.30% Mg, max. 0.05% Mn, and max. 0.04% Cu. The strip is produced from a continuous cast ingot of the above composition which is hot rolled to a thickness of up to 2-7 mm. The residual resistance ratio of the hot rolled strip is RR=10-20. The cold rolling is carried out with or without intermediate annealing, wherein the degree of rolling reduction after intermediate annealing is >60%. The further processing up to the EC roughening takes place with the microstructure adjusted in the rolling process at <100° C. The litho strip is characterized by a high thermal stability, a good roughening behavior in the EC processes, and a high reverse bending fatigue strength perpendicular to the rolling direction.Type: GrantFiled: September 10, 2004Date of Patent: June 23, 2009Assignee: Hydro Aluminium Deutschland GmbHInventors: Wolfgang Von Asten, Bernhard Kernig, Barbara Grzemba
