Search Symbol (Half-width)	Description of Search Symbols
Space	"AND" indicates the intertwining of key terms used in a search
Double Quotation Marks ("") ( " " )	Double quotation marks indicate the beginning and end of a phrase, and the search will only include terms that appear in the same order of those within the quotations. Example: "image process" ： " image process "
?	Indicates a variable letter. Entering two ? will indicate two variable letters, and so on. Example: "Appl?", search results will yield apple, apply… e , appl y … ( (often used to English word searches) )
*	Indicates an unlimited number of variable letters to follow, from 1~n. Example: Enter "appl*", search results will yield apple, apples, apply, applied, application…(often used in English word searches) e , appl es , appl y , appl ied , appl ication … ( (often used to English word searches) )
AND、OR、NOT	Boolean logic combinations of key words is a skill used to expand or refine search parameters. (1) AND (1) AND: Refines search parameters (2) OR (2) OR: Expands search parameters (3) NOT: Excludes irrelevant parameters

DOI stands for Digital Object Identifier （ D igital O bject I dentifier ） ,
and is the unique identifier for objects on the internet. It can be used to create persistent link and to cite articles.

Using DOI as a persistent link

To create a persistent link, add「http://dx.doi.org/」「 http://dx.doi.org/ 」 before a DOI.
For instance, if the DOI of an article is 10.5297/ser.1201.002 , you can link persistently to the article by entering the following link in your browser: http://dx.doi.org/ 10.5297/ser.1201.002 。
The DOI link will always direct you to the most updated article page no matter how the publisher changes the document's position, avoiding errors when engaging in important research.

Cite a document with DOI

When citing references, you should also cite the DOI if the article has one. If your citation guideline does not include DOIs, you may cite the DOI link.

DOIs allow accurate citations, improve academic contents connections, and allow users to gain better experience across different platforms. Currently, there are more than 70 million DOIs registered for academic contents. If you want to understand more about DOI, please visit airiti DOI Registration （ doi.airiti.com ）。

Parallel Abstract 〈TOP〉

In the first part of this thesis, we describe preparation and measurements of use MBE-grown Al thin films with four different thicknesses (12, 16, 20 and 60 nm) and then present the information from AFM and XRD patterns of the flims we judge the structures of the four films. Furthermore, by studying superconductivity of the films and comparing the experimental results with the previous theories we analyze the details of the Al structures. We had measured the normal resistivity  , the critical temperature Tc, the critical filed Hc, the critical current density Jc as the judging parameters and calculated the mean free path l by Drude model and several corrections to discuss the homogeneity of the structures. We also observe the variation of the superconducting classification with different corrections of l and discovery that the mean free path indeed influences the classification by altering the penetration depth and the coherence length. The corrections of l are in consideration of size effect, granular boundary scattering, electron localization, etc. In the second part of this thesis, we describe preparation and measurements of E-gun-grown Al thin films with two different thicknesses (30 and 60 nm) and undertake the same research as that done on the MBE-grown films. Finally, we compare the structures and superconductivity of the MBE and E-gun films. We suggest that the grains of the E-gun-prepared films are more complete and smaller.
