Homework Statement
ZnSe is a II-VI semiconductor and a very useful optical material used in various applications such as optical windows (especially high power laser windows), lenses, and prisms. It transmits over 0.50-19 μm. Refractive index, n in the 1-11 μm range is described by a Cauchy expression of the form
Homework Equations
The Attempt at a Solution
Given the index of refraction by the following Cauchy equation relationship
n-2, n0, n2, and n4 such that
λ = 1000000
into the very first expression for n.Typically hυ is given in eV (electron volts). For n to be dimensionless, wouldn't hc have to be equal to eV (a unit of energy) as well? But obviously energy has units of hc/λ. So something is wrong. How do I take into account the fact that λ is given in micrometers in finding the coefficients?
I know I am close, but I can't finish it up. :(
