采用边界元法模拟了适合于场致发射的亚纳米石墨片的场增强因子。研究了矩形板的边和角表面上增强因子的变化规律。已发现增强因子对板的厚度、高度和宽度的依赖性，并且在可能的情况下通过简单的经验函数将结果参数化。© 2008 Elsevier BV保留所有权利。
The Boundary Element Method has been used to model the field enhancement factors of free-standing sub-nanometre graphite sheets, which are thought to be suitable for use as field emission sources. The variation of the enhancement factor over the surfaces of the edges and corners of the rectangular sheets has been explored. The dependence of the enhancement factor on the thickness, height and width of the sheets has been found and the results have been parameterized where possible by simple empirical functions.© 2008 Elsevier BV All rights reserved.
