Materials can handle the following arguments:
Function |
Meaning |
---|---|
(n at 540 nm) |
Returns the real part of the refractive index of the object at 540 nm. You can use alternative spectral units like 1/cm or eV if you like. |
(k at 540 nm) |
This function returns the imaginary part of the refractive index of the object at 540 nm. |
(alpha at 540 nm) |
Returns the absorption coefficient (in 1/cm) of the object at 540 nm. |
(alpha1E4) |
Returns the wavenumber for which the absorption coefficient has the value 10000 1/cm. This position is sometimes used to quantify the electronic gap. This function will work properly only if the following rules are satisfied: 1. The absorption coefficient of the material is below 10000 1/cm for large wavelengths and above 10000 1/cm at small wavelengths. 2. There is only one position in the spectral range of the material where the absorption coefficient has the value 10000 1/cm. If the position cannot be identified a value of 0 is returned. |
(carrier concentration) |
If there is a Drude model or an extended Drude model used in the material object, the carrier concentration is computed and returned using the unit 1020 cm-3.( |
(conductivity) |
If there is a Drude model or an extended Drude model used in the material object, the conductivity is computed and returned using the unit Ω-1 cm-1. |
(resistivity) |
If there is a Drude model or an extended Drude model used in the material object, the resistivity is computed and returned using the unit Ω cm. |
(mobility) |
If there is a Drude model or an extended Drude model used in the material object, the mobility is computed and returned using the unit cm2 V-1 s-1. |
