Collective Classical and Quantum Fields: In Plasmas, Superconductors, Superfluid 3he, and Liquid Crystals

為了解決Aluminium can的問題，作者Kleinert, Hagen 這樣論述：

This is an introductory book dealing with collective phenomena in many-body systems. A gas of bosons or fermions can show oscillations of various types of density. These are described by different combinations of field variables. Especially delicate is the competition of these variables. In superflu

id 3He, for example, the atoms can be attracted to each other by molecular forces, whereas they are repelled from each other at short distance due to a hardcore repulsion. The attraction gives rise to Cooper pairs, and the repulsion is overcome by paramagnon oscillations. The combination is what fin

ally led to the discovery of superfluidity in 3He. In general, the competition between various channels can most efficiently be studied by means of a classical version of the Hubbard-Stratonovich transformation.A gas of electrons is controlled by the interplay of plasma oscillations and pair formati

on. In a system of rod- or disc-like molecules, liquid crystals are observed with directional orientations that behave in unusual five-fold or seven-fold symmetry patterns. The existence of such a symmetry was postulated in 1975 by the author and K Maki. An aluminium material of this type was later

manufactured by Dan Shechtman which won him the 2014 Nobel prize. The last chapter presents some solvable models, one of which was the first to illustrate the existence of broken supersymmetry in nuclei.

三相電磁噴流之研究

為了解決Aluminium can的問題，作者鄭力瑋 這樣論述：

摘要電磁噴流是一種運用磁流體力學(Magnetohydrodynamics, MHD)之概念，當給予電極板電能與固定磁場時，便可產生勞倫茲力，藉此推動導電流體。其優點在於致動原理簡易，且不需要依靠複雜的機械結構，便可實現推送之效果。常見的應用在微尺度之微動幫浦與大型船體無槳式推進器上，以往許多研究都著重在電場與磁場之設計與幾何構型的最佳化，而本研究透過實驗探討在電磁噴流中，電極板附帶產生電化學反應而生成氣泡所構成之多相噴流場。並藉由染劑與氣泡之方式發展一流場可視化之方法。本研究透過計算染劑之汙染面積並與數值模擬結果進行比較，發現在低電流時之預測流量結果較為相近。並定義一無因次參數為勞倫茲力雷

諾數(Re_L)，用以描述電磁噴流之流場型態，實驗結果透過定性觀察當勞倫茲力雷諾數(Re_L)大於1600時，噴流型態會發展成紊流的型式。透過無因次分析結果也顯示其噴流擴散角(θ)與氣泡佔比(Ag)有隨Re_L數增加而有上升之趨勢，且在Re_L數大於1600後，因流場型態轉變，擴散角與氣泡佔比也有明顯上升之現象。在最後討論使用鋁電極板對於電磁噴流之影響。

Solidification and Solid-state Transformations of Metals and Alloys

為了解決Aluminium can的問題，作者Hernandez, Maria Jose Quintana/ Pero-sanz, Jose Antonio/ Verdeja 這樣論述：

Solidification and Solid-State Transformations of Metals and Alloys describes solidification and the industrial problems presented when manufacturing structural parts by casting, or semi-products for forging, in order to obtain large, flat or specifically shaped parts. Solidification follows the nuc

leation and growth model, which will also be applied in solid-state transformations, such as those taking place because of changes in solubility and allotropy or changes produced by recrystallization. It also explains the heat treatments that, through controlled heating, holding and cooling, allow t

he metals to have specific structures and properties. It also describes the correct interpretation of phase diagrams so the reader can comprehend the behaviour of iron, aluminium, copper, lead, tin, nickel, titanium, etc. and the alloys between them or with other metallic or metalloid elements.This

book can be used by graduate and undergraduate students, as well as physicists, chemists and engineers who wish to study the subject of Metallic Materials and Physical Metallurgy, specifically industrial applications where casting of metals and alloys, as well as heat treatments are relevant to the

quality assurance of manufacturing processes. It will be especially useful for readers with little to no knowledge on the subject, and who are looking for a book that addresses the fundamentals of manufacturing, treatment and properties of metals and alloys.Uses theoretical formulas to obtain realis

tic data from industrial operationsIncludes detailed explanations of chemical, physical and thermodynamic phenomena to allow for a more accessible approach that will appeal to a wider audienceUtilizes micrographs to illustrate and demonstrate different solidification and transformation processes

具有綠光雷射結晶多晶矽通道之T型閘薄膜電晶體射頻特性分析

為了解決Aluminium can的問題，作者葉宇婕 這樣論述：

本論文中，我們研究具有T型閘極、空氣邊襯及矽化閘/源/汲極多晶矽薄膜電晶體的射頻特性。為了提升多晶矽薄膜的晶粒尺寸，我們使用綠光奈秒雷射來製備厚度為50 nm與100 nm的多晶矽薄膜。結果顯示厚度為100 nm的薄膜能得到等效尺寸大於1 μm的晶粒大小，遠優於50 nm厚的多晶矽薄膜。我們於元件製作時採用了新穎的T型閘極技術，不僅降低元件的閘極電阻，也使電晶體具有比微影技術解析極限更小的閘極線寬，使轉導得以大幅提升。我們也分別利用高溫的快速熱退火及低溫的微波退火來活化源汲極雜質。在通道厚度為100 nm並以快速熱退火進行源汲極活化的多晶矽薄膜電晶體中，對最小通道長度達124 nm之元件，截

止頻率可達59.7 GHz，最大震盪頻率亦可達34 GHz。具有相同通道厚度並以微波退火來活化雜質的電晶體中，當通道長度微縮至102 nm，元件的截止頻率更高達63.6 GHz，最大震盪頻率亦可達29.7 GHz。相較過往文獻報導的多晶矽薄膜元件，我們以微波活化源汲極的薄膜電晶體達到了最高的截止頻率。
