| dc.description.abstract | 我們將金屬原子蒸鍍在氧化鋁/鎳鋁合金(100)基板上，成功製作出具有以下優點的金屬奈米顆粒：有序的排列、均勻的體積分佈以及高熱穩定度。而這些優點歸因於氧化鋁層表面產生獨特的週期性一維長條結構，其間距約4 nm。我們分別在低溫、室溫及高溫下成長金屬奈米顆粒藉以比較其有序性的不同。此外，我們改變不同的原子覆蓋量來研究其熱穩定度與磁性行為。這個新穎的奈米結構材料或許能為各式各樣的應用打開大門，例如：更有效的催化劑、更高的資料儲存密度…等，而製作出大面積有序排列的奈米顆粒是這些應用的重要條件之一。 | zh_TW |
| dc.description.abstract | We present metal nanoparticle grown by vapor deposition over a single-crystalline Al2O3 layers on NiAl(100) with excellences including: well-ordered alignment, uniform size distribution, and high thermal stability. We attribute the excellences to peculiar one-dimensional long stripes with ~ 4 nm interdistance on the surface of the ultrathin Al2O3 template. For the comparism, low temperature, room temperature and high temperature growth of nanoparticles are performed. Besides, the thermal stability and the magnetic properties with respect to different deposition amount are also characterized. This novel nanostructure may open the door to numerous applications, such as catalysis and nanostorage, where large area well-ordered nanoparticles are desired. | en |
