本文讨论了研究半导体缺陷深能级瞬态谱中遇到的多指数分解问题，并使用共轭梯度计算法对瞬态谱进行数值lAPlACE逆变换处理来实现多指数瞬态的分解.结果表明，此方法具有较高的分辨率，而且存储和计算量较小，适用于进行常规的深能级瞬态精细结构测量.The problem of decomposing a multiple exponential transient into its constituent parts in study of deep energy levels in semiconductors is discussed.To deconvolute a multiple exponential transient, conjugate gradient method is used to perForm numerical inverse Laplace transForm by a personal computer.The results show that this method is not only of high resolution, but also requires less memory and calculation, which is sui table For study of Fine structure of deep level transient.国家及福建省自然科学基
