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〉

X-ray spectroscopy and transmission electron microscopy were utilized to study the electronic property and microstructure of diamond thin films. The grain size of diamond films grown by chemical vapor deposition (CVD) can be controlled by varying the synthesizing conditions, such as plasma gas composition, temperature, pressure and the applied bias voltage. Near edge x-ray absorption fine structure (NEXAFS) measurements indicate that the intensity ratio of sp2 to sp3 (sp2/sp3) increases with decreasing grain size of diamond films. The sp2/sp3 ratio of UNCD films can be adjusted by post deposition surface treatments. The bias voltage treated film has the highest sp2/sp3 ratio compared to the as-grown, air plasma or hydrogen plasma treated films. The sp2/sp3 ratio is related to the turn on field (E0) of electron field emission (EFE) and the electron current density (Je). Samples with the higher sp2/sp3 ratio are found to have the lower E0 and the higher Je. The TEM and EELS studies of high energy Au-ion irradiated diamond films indicate that some diamond grains in MCD are disintegrated and the amorphous carbon phase around the grain increases due to the ion irradiation. On the other hand, in Au-ion irradiated UNCD films, graphite and other carbon phases around the grains increase and there are no significant changes in grain size. It is also observed that, in UNCD, there is a systematic correlation between the fluency of Au-ion and the EFE properties (E0 and Je). This phenomenon facilitates a potential application of UNCD films as a radiation detection material.
