摘要
根据电化学 C-V测量 AlGaInP外延片获得的载流子浓度深度分布数据,以及其 LED外延片封装后的工作电压,计算了其中B+-N与P+-P两种同型结的接触电势差,指出调制掺杂同型结的掺杂浓度分布是影响LED工作电压的另一大因素,并提出了进一步降低 LED工作电压的有效措施.
Based on the results of AlGaInP LED samples measured by electro-chemical C-V profiler and their work voltages, we analyzed the contact-voltage difference from the homo-junctions, such as N+-N and P+-P junction, pointed out that the carrier density distribution of the modulated doping have a distinctive effect on the work voltage of HB-LED, and presented the method decreasing further HB-LED's work voltage.
