论文摘要
在本文中，我们表明，非泵发光二极管（LED）的波长的变化实际上是线性的，这是Varshni广泛接受的经验表达的新结果。该公式对大多数半导体从0K到其高温极限的带隙变化，但要遵守拟合参数。因此，我们建议一种外部热机制，可用于调整恒定偏置LED的波长并稳定其波长。此外，我们演示了已发布的ALN数据的方法，并表明拟合参数既遵循）。此外，我们建议一种表征半导体的新方法。最后，我们介绍了几个商业LED的实验测量结果。
In this article, we show that the variation of the wavelength of a non-pumped light-emitting diode (LED) is practically linear with temperature, a novel consequence of Varshni's widely accepted empirical expression. This formula models the bandgap variation for most semiconductors from 0K to their high-temperature limits, subject to fitting parameters. Therefore, we suggest an external thermal mechanism that can be used to tune the wavelength of a constant-current biased LED and also to stabilize its wavelength. Furthermore, we demonstrate the approach on published AlN data and show that the fitting parameters follow trivially. In addition, we suggest a novel method to characterize semiconductors. Finally, we present the results of experimental measurements on several commercial LEDs.
