Fabrication and Emission Properties of Stable Dual Ion/Electron Point Sources
No full text我們利用銦鉍合金可製造出一種穩定的雙重點狀離子／電子發射源。把銦鉍合金作為液態金屬離子源時，低熔點的特性使他跟商業化的產品-鎵離子源一樣擁有非常好的離子發射性質。在離子源冷卻凝固之後，我們用場發射電子顯微術去研究其電子發射特性。我們也證明利用電化學蝕刻鎢針，可以改進銦鉍合金的電子發射性質，使它能跟目前所發現到具有最好電子發射特性的金銦合金離子／電子發射源之性質相接近。而在研究強電子發射與發射源表面形貌之間的關係時，我們也觀察到一個有趣的現象﹕鎢針鍍上銦之後，在長時間強電子發射下，原本堅固的鎢金屬會產生原子遷移。而這個遷移傾向於形成一個穩定的特殊幾何結構。我們發現鍍上銦的鎢針在經過這樣的過程之後，可以被用作一個擁有非常好電子發射特性的雙重點狀離子／電子發射源。對於未來更進一步發展單軸聚焦離子／電子束系統來說，銦鉍合金離子／電子發射源的發展以及適當地調控發射源，都是重要的突破。We fabricate a stable dual ion/electron point source based on In-Bi alloy. As a liquid metal ion source (LMIS), its emission performance at about 70 – 100℃ is comparable to that of commercial Ga-LMIS. After the In-Bi source is solidified, field electron microscopy is employed to study the pattern of electron emission. In-Bi alloy is inherently soft so that its electron emission is easy to be unstable. To remedy this disadvantage, the In-Bi alloy is loaded onto a sharp tungsten tip fabricated by electrochemical etching. The resulting source exhibits electron emission characteristics comparable to that of Au-In alloy.
We also investigate the correlation between surface morphology of an In/W emitter and its electron emission behavior and observe that, after long-term electron emission, some underlying W migrates to the surface. We attribute the tungsten migration to high electron emission current density. Interestingly, the migration leads to a protrusion with specific geometry on the apex of tip and such an In/W emitter constitutes a dual ion/electron emitter with good electron emission properties. Furthermore, stable ion and electron emission can be interchangeably extracted from the source. Both the successful fabrication of the In-Bi/W and In/W stable dual ion/electron point sources are important steps towards the further development of single-column focused ion/electron beam systems.Chapter 1

No full textThis report discusses the works of four Russian composers spanning from the early to the late nineteenth century. The early nineteenth century pieces include Pyotr Tchaikovsky\ue2s Nocturne Op. 19, No. 4, and Pezzo Capriccioso Op. 62, as well as Sergey Rachmaninoff\ue2s Pr\uc3\ua9lude et Danse Orientale Op. 2. The end of the nineteenth century pieces are Dmitri Shostakovich\ue2s The Second Waltz from Suite for Variety Orchestra Op. 99, and Nikolai Myaskovsky\ue2s Sonata for Cello and Piano Op. 81.
Tchaikovsky and Rachmaninoff\ue2s pieces mentioned above are both originally written for piano and was later transcribed for well-known cellist Anatoly Brandukov (1859-1930). Myaskocsky\ue2s cello sonata and Shostakovich\ue2s \ue2Waltz No. 2\ue2 were composed under the pressure of the Russian government. Although these four works were completed under different circumstances and political factors, the Rusiian style remained evident. I will introduce the background of these works of their style, and their interpretation
The Global Economic Recession and Industrial Structure: Evidence from Four Asian Dragons
Get PDFThe collapse of exports that has attended the current global economic recession threatens the export-led economic growth of the four Asian dragons. To better understand the economic performances and future prospects of the four dragons, this paper first examines the economic structural changes that have taken place in Hong Kong, China; the Republic of Korea; Singapore; and Taipei,China, as well as the gradual shifting of the sources of economic growth away from the manufacturing sector and toward the service sector. Following this, a panel data set for the four dragons for the period 1995–2008 is constructed and a fixed-effects model applied to the data.global economic recession; asian dragons; new service development; industrial structure
