A comment on the dependence of LED's efficiency on the junction ideality factor

摘要

P-n junctions form the basic building blocks for any semiconductor device. Therefore, the complete understanding of the junction characteristics is very important. Although being a widely discussed topic in electronics, there are still some gaps such as finding the value and significance of the junction ideality factor, that needs to be addressed. In this article we have discussed the problems faced while extracting the ideality factor from the I-V characteristics of a p-n LED and its significance in device performance.
