Calculation of Bimolecular Recombination Coefficient and Internal Quantum Efficiency of β-FeSi2 DH LED

The analytical methods to calculate the bimolecular recombination coefficient B and internal quantum efficiency η of β-FeSi
₂
DH LED are developed in this paper. The calculated B of β-FeSi
₂
is 1.28×10
^-10
(cm
³
/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 η values are discussed in this paper.
