The linear relation of gain on carrier density in the conventional rate equation is replaced by the logarithmic relation for quantum well lasers in this paper.
首次在理论上用量子阱激光器增益与载流子密度的对数关系替代了原有速率方程中的线性关系，得到了改进了的速率方程，分析了稳态和调制特性。
Corrosion of metals is a kind of irreversible phenomena of consumption under action of aggressive medium in use of metals.
不锈钢、碳钢、黄铜裸电极在电解质溶液中氧化膜的载流子密度均随浸泡时间的延长而逐渐增大。
Further analysis shows that it is caused by the enhancement of the threshold current density and threshold carrier density in terms of optical-gain spe.
进一步分析认为,这是因为条宽变窄导致器件阈值电流密度、阈值载流子密度变大造成的。
Comparison of measuring methods of sheet carrier density in AlGaN/GaN heterostructures;
AlGaN/GaN异质结载流子面密度测量的比较与分析
Based on the principles and experimental results of two-beam coupling,theeffective carrier density in pure LiNbO3 and Fe: LiNbO3 crystals has been calculated.
基于双光束耦合的原理及实验结果，计算了纯ＬｉＮｂＯ３和Ｆｅ：ＬｉＮｂＯ３晶体中的有效载流子密度，对结果进行了讨论，指出光折变ＬｉＮｂＯ３中氧空位色心也是载流子施主之一，且被激发的Ｆｅ２＋仅占晶体中Ｆｅ２＋浓度的一小部分。
