Mahan, A Clarification of the Index of Refraction of Beta-Iron Disilicide, Journal of Applied Physics 64, no. 4 (15 August 1988): 2034-2037.http://hdl.handle.net/10217/67930Previously published values of the index of refraction of beta-iron disilicide are corrected. Based on improved measurements and analysis, the undispersed value of the refractive index is 5.6. The previously published analysis of the absorption coefficient showed that the material possesses a direct forbidden energy gap of approximately 0.87 eV. The type of the transition is unchanged, but the band-gap value is slightly shifted to 0.89 eV.born digitalarticleseng©1988 American Institute of Physics.Copyright and other restrictions may apply.
