Measuring the motions of charge carriers on femtosecond timescales provides a window into the most elementary processes that occur in matter. Technologies like solar cells, transistors, and photodetectors all depend upon the rapid movement of electrons over distances measured in nanometres. The success or failure of these technologies depends, in large measure, on our ability to predict and control these ultrafast processes. In addition the function of several biomolecules depends upon either photo-initiated electron transfer events or long range charge conduction. In general, a detailed understanding of charge transport processes provides far-reaching insight across many disciplines in the physical sciences.

在飞秒时间尺度上测量电荷载流子的运动提供了一个了解物质中发生的最基本过程的窗口。 太阳能电池、晶体管和光电探测器等技术都依赖于电子在纳米级距离上的快速运动。 这些技术的成败在很大程度上取决于我们预测和控制这些超快过程的能力。 此外，几种生物分子的功能取决于光引发的电子转移事件或长程电荷传导。 总的来说，对电荷传输过程的详细了解为物理科学中的许多学科提供了深远的见解。
