基于高频方波电压激发电致发光效应的电场可视化与定量分析

To achieve the visualization and quantitative analysis of electric fields for direct bond copper (DBC) substrate, the characteristics of square wave excitation electroluminescence (EL) are investigated to develop the electric field reversion model. Initially, the single photon counting technique and luminescence spectroscopy of EL devices are carried out to reveal the luminescence mechanism. Then,...
