KKkton - a program for Kramers-Kronig (KK) analysis of optical data.
The KK analysis is carried out using the extinction coefficient (k) as input and the refractive index (n) is calculated. Low energy Drude and high-energy Lorentz extrapolations are used and parameters for these need also to be inputs. The Matlab program contains a routine for calculating reflectance (R) and transmittance (T) for a film on a substrate and comparing with experimental R and T that need to be entered into the program. kdata.txt is an example of an input file of k-data. See attached files for detailed instructions and program files.
