摘要註:
目前地球環境持續惡化且日益受到注視的情況之下,減少能源消耗以及綠色環保將是未來科技發展不容忽視的重要課題。 本論文乃利用具生物親合性的聚賴胺酸(Poly-L-Lysine, PLL)與聚穀胺酸(Poly-L-Glutamic acid, PLGA)作為媒介材料,以逐層組裝技術(Layer by Layer, LbL)鍍製聚胺基酸多層薄膜於二氧化矽基板上,並利用此薄膜輔助合成金奈米粒子以及矽氧化物,最後使用溶膠凝膠法製備二氧化鉿控制氧化層並鍍製上鋁電極後,即完成奈米晶體記憶體元件。此製程的特點為水相全溶液製程,過程中不需使用到有機溶劑且製程相當簡便,相當符合近年來綠色化學的趨勢。我們主要探討了以下實驗參數:(1)聚胺基酸的還原能力,(2)聚胺基酸薄膜的鍍製特性,(3)還原金奈米粒子之影響條件,(4)金奈米粒子穩定性探討,與(5)奈米晶體記憶體特性探討。 由實驗結果得知:(1)聚穀胺酸的還原能力較聚賴胺酸優,且分子量愈低所還原的金奈米粒子粒徑較小。若比較官能基的還原能力方面,帶有負電荷的(COO-)羧基應較氨基(NH3+)為強;(2) 高分子量聚胺基酸所鍍製的薄膜愈均整,且聚賴胺酸為頂層薄膜時,薄膜的粗糙度較低;且在不同的酸鹼值環境下鍍製的結果也有所不同;(3) 在酸鹼值約為6時以聚胺基酸薄膜所得到的奈米粒子條件最佳,平均粒徑為4.5nm,整體密度為1.72ⅹ1012cm-2;(4)利用聚胺基酸薄膜析出的矽氧化物能使金奈米粒子具備一定的熱穩定性;(5)在記憶元件特性探討中,奈米粒子密度較高展現出的特性愈佳。 Under the continued deterioration of the global environment and the increasingly getting more attention, reducing energy consumption and environmental protection will be an important issue in the future technological development. In this work, we used biocompatible Poly-L-Lysine (PLL) or Poly-L-Glutamic acid (PLGA) as medium. The multilayers of PLL/PLGA were fabricated by applying Layer-by-Layer (LbL) assembly process on SiO2 substrate. The formation of gold nanoparticles and silica were both mediated by the polypeptide multilayers. After covering the nanoparticles by spin coating of sol-gel-synthesized HfO2 control oxide, Al electrode was deposited to construct a nanocrystal memory device. This study proposed a water-based all-solution process without the use of organic solvent. This process is quite simple and consistent with the recent trend of green chemistry. In this study, several issues are discussed as below: (1) the reducing ability of poly amino acid, (2) characterization of the multilayer film of poly amino acid, (3) reduction conditions of gold nanoparticles, (4) stability of gold nanoparticles, (5) memory properties of nanocrystal memory. The experimental results showed : (1) Reducing ability of PLGA is stronger than that of PLL. And the reducing ability of carboxyl group is stronger than that of amino group by comparing the characterization of functional group in poly amino acid. The poly amino acid with a lower molecular weight induced the formation of gold particle with smaller particle size. (2) The poly amino acid with higher molecular weight assembled to a smoother film, but also depending on the solution pH value. (3) A superior reduction result of gold nanoparticles with average particle size about 4.5nm and total particle density of 1.72ⅹ1012cm-2 was obtained at solution pH value about 6. (4) The poly amino acid mediated silica can serve as protection layer, improving the thermal stability of gold nanoparticles. (5) The nanocrystal memorywith higher particle density showed better memory property.
