Forouhi bloomer
WebThe Forouhi-Bloomer (FB) model describes the Refractive Index, n, and the Extinction Coefficient, k, as functions of wavelength, λ, and was derived based on first principles quantum mechanics. The scientific derivations of the FB model were originally published in 1986 and 1988, and a related patent was subsequently granted in 1990. WebJan 22, 2010 · The optical properties are well described with the Forouhi–Bloomer model. Both the band gap and optical properties show a strong dependence on the film thickness. For film thickness smaller than ∼ 10 nm, a band gap expansion is observed as compared to bulk crystalline Ge, which is attributed to the one-dimensional quantum …
