论文摘要
研究了有助于当代框架内冷场排放电流准确性的因素。已经发现,只要使用线性化的局部电流密度来评估净电流,误差的主要来源就是选择泰勒扩展的能量,但在选择到达近似游戏系数的方法的选择上并不是那么多。线性化能量的合适选择和Kemble校正的实施,可以将错误限制在各种局部领域的3 \%以下。
The factors that contribute to the accuracy of the cold field emission current within the contemporary frameworks are investigated. It is found that so long as the net current is evaluated using an expression for the local current density obtained by linearizing the Gamow factor, the primary source of error is the choice of the energy at which the Taylor expansion is done, but not as much on the choice of the method used to arrive at the approximate Gamow factor. A suitable choice of linearization energy and the implementation of the Kemble correction, allows the restriction of errors to below 3\% across a wide range of local fields.
