Ge database n/k values #93

Closed phoebe-p closed 4 years ago

phoebe-p commented 4 years ago

The current database values for Ge n and k data only have k (extinction coefficient) data up to 1550 nm, the lowest direct bandgap of Ge (0.8 eV). This means any indirect absorption in Ge below 0.8 eV, above the indirect bandgap 0.66 eV, is not taken into account. Data should be replaced going up to at least 1900 nm.

Do you know any source for this?

phoebe-p commented 4 years ago

Yes, sorry, I have the data (same data I use to fit ellipsometry data). Just making the issues to keep track of things!
