Abstract
针对类金刚石薄膜热力学性质的研究对于准确建立热辅助磁记录硬盘多层结构的传热模型非常关键.本文采用分子动力学方法研究类金刚石薄膜模型的建立及法向导热系数的预测.类金刚石模型通过对已有Tersoff势函数进行延长截断的修正后使用淬火法建模的方式获得,模拟得到的类金刚石密度与sp3杂化率的变化趋势与已有文献一致.基于非平衡分子动力学方法,计算了金刚石和类金刚石薄膜的法向导热系数.前者随有效导热长度的增加而增大,在300 K到700 K之间随温度的升高而降低,与已有文献一致.后者随其有效导热长度以及sp3杂化率的增加而增大.本工作为建立热辅助磁性存储技术下的硬盘多层材料的传热模型提供了基础.
