20140097502 | SEMICONDUCTOR DEVICE AND FABRICATING METHOD THEREOF - A semiconductor device has gate-all-around devices formed in respective regions on a substrate. The gate-all-around devices have nanowires at different levels. The threshold voltage of a gate-all-around device in first region is based on a thickness of an active layer in an adjacent second region. The active layer in the second region may be at substantially a same level as the nanowire in the first region. Thus, the nanowire in the first region may have a thickness based on the thickness of the active layer in the second region, or the thicknesses may be different. When more than one active layer is included, nanowires in different ones of the regions may be disposed at different heights and/or may have different thicknesses. | 04-10-2014 |

20120111801 | Near-Field Photocatalyst Including Zinc Oxide Nanowire - Disclosed is a near-field photocatalyst using a ZnO (ZnO) nanowire. The photocatalyst is advantageous in that low-priced zinc is used instead of titanium, conventionally used as a photocatalyst to reduce expenses, and that it is possible to obtain overvoltage which is sufficient to generate hydrogen using an optical near field formed around an end of a ZnO nanowire without the application of additional external voltage, thus the use of a costly electrode, such as platinum, is avoided and a process is simplified. | 05-10-2012 |
