Abstract :
The analytical methods to calculate the bimolecular recombination coefficient B and internal quantum efficiency etamiddot of beta-FeSi2 DH LED are developed in this paper. The calculated B of beta-FeSi2 is 1.28 times 10-10 (cm3/sec), which value is similar to that of InP. The diffusion and thermionic emission mechanisms are used to calculate the free electron current densities and the rate equation is used to calculate the internal quantum efficiency. The effects that influence etamiddot values are discussed in this paper.
