Functional Analysis, Calculus of Variations and Numerical Methods for Models in Physics and Engineering

為了解決Dimensional shape的問題，作者Botelho, Fabio Silva 這樣論述：

The book discusses basic concepts of functional analysis, measure and integration theory, calculus of variations and duality and its applications to variational problems of non-convex nature, such as the Ginzburg-Landau system in superconductivity, shape optimization models, dual variational form

高功率可變出光角光子晶體面射型雷射之特性研究

為了解決Dimensional shape的問題，作者陳立人 這樣論述：

本論文旨在研究高功率可變出光角之光子晶體面射型雷射的設計，製作及其光電特性。光子晶體面射型雷射因具備大功率操作及發散角小等特性，近年來頗受矚目，被視為是3D感測，光達，和雷射加工等應用領域的理想光源；研究首先藉由數值模擬計算來探討磊晶結構及光子晶體結構對於雷射閾值及出光效率的影響，進而得到較佳的磊晶結構同時配合不同的光子晶體結構來進行實驗驗證，實驗與模擬的結果均顯示雷射的斜率效率隨著光子晶體結構的對稱性下降而大幅上升，實驗並針對P面向上的結構進行優化，使得光輸出功率進一步提升，同時我們也針對大功率單模操作進行探討。另一方面我們也針對改變鐳射出光角度的機制進行研究以實現光束掃描的新奇雷射結構。

先後評估了主動式的光學相位陣列，主動式光柵結構，雙調變式光子晶體結構以及超穎結構等方式，考量結構整合的便利性及發光效率等因素，我們採用雷射整合表面超穎結構的方式進行設計，超穎結構的設計使用了奈米結構陣列及反向設計兩種方式，在砷化鎵基板上實驗的結果顯示此結構可將雷射光偏轉至設計的角度並且抑制原本垂直方向上的雷射光，此超穎結構結合光子晶體面射型雷射將得到高效率且緊湊的光束偏轉雷射，進一步製作成不同出光角度的陣列並單獨控制即可實現掃描功能，預期此雷射結構在上述的應用領域有著相當大的潛力。

二維材料於邏輯元件與記憶體內運算應用

為了解決Dimensional shape的問題，作者鍾昀晏 這樣論述：

半導體產業在過去半個世紀不斷地發展，塊材材料逐漸面臨電晶體微縮的物理極限，因此我們開始尋找替代方案。由於二維材料天生的原子級材料厚度與其可抑制短通道效應能力，被視為半導體產業極具未來發展性材料。此篇論文為研究二維材料二硫化鉬的N型通道元件之製作技術與其材料的特性與應用。首先，我們使用二階段硫化製程所製備的二硫化鉬沉積高介電材料並使用X-射線能譜儀（XPS）與光致發光譜（PL）進行分析，量測二硫化鉬與四種高介電材料的能帶對準，參考以往製程經驗，可結論二氧化鉿是有潛力介電層材料在二硫化鉬上，並作為我們後續元件的主要閘極介電層。接著使用二階段硫化法製作鈮（Nb）摻雜的二硫化鉬，Ｐ型的鈮摻雜可提升載

子摻雜濃度用以降低金半介面的接觸電阻，透過不同製程方式製作頂部接觸和邊緣接觸的兩種金半介面結構，傳輸線模型(TLM)分析顯示出，邊緣接觸結構比頂部接觸結構的接觸電阻率低了兩個數量級以上，並藉由數值疊代方式得知層間電阻率是導致頂部接觸結構有較高接觸電阻率主因，並指出邊緣接觸之金半介面在二維材料元件的潛在優勢。在電晶體研究上，我們使用化學氣相沉積（CVD）合成的二硫化鉬成功製作出單層Ｎ型通道元件，將此電晶體與記憶體元件相結合，用雙閘極結構將讀（read）與寫（write）分成上下兩個獨立控制的閘極，並輸入適當脈衝訊號以改變儲存在電荷儲存層的載子量，藉由本體效應（Body effect）獲得足夠大的

記憶區間（Memory window），可擁有高導電度比（GMAX/GMIN = 50）與低非線性度（Non-linearity= -0.8/-0.3）和非對稱性（Asymmetry = 0.5），展示出了二維材料在類神經突觸元件記憶體內運算應用上的可能性。除了與記憶體元件結合外，我們亦展示二維材料電晶體作為邏輯閘的應用，將需要至少兩個傳統矽基元件才可表現的邏輯閘特性，可於單一二維材料電晶體上展現出來，並在兩種邏輯閘（NAND/NOR）特性作切換，二維材料的可折疊特性亦具有潛力於電晶體密度提升。我們進一步使用電子束微影系統製作奈米等級短通道元件，首先使用金屬輔助化學氣相沉積 (Metal-as

sisted CVD)方式合成出高品質的二維材料二硫化鎢 (WS2)，並成功製作次臨界擺幅（Subthreshold Swing, S.S.）約為97 mV/dec.且高達106的電流開關比（ION/IOFF ratio）的40奈米通道長度二硫化鎢Ｐ型通道電晶體，其電特性與文獻上的二硫化鉬N型通道電晶體可說是相當，可作為互補式場效電晶體。另一方面，深入了解二維材料其材料特性後，可知在厚度縮薄仍可保持極高的機械強度，有潛力作為奈米片電晶體的通道材料。故於論文最後我們針對如何透過對元件製作優化提供了些許建議。
