Hello PF,
I came across a fact that, tungsten, molybdenum and chromium all have 6 valence electrons.
Now,if one uses Molybdenum and Chromium instead of tungsten in photonic crystals for TPV(Thermo PhotoVoltaics) does it mean:
1. All are capable of releasing equal number of photons, because of electron hole diffusion?
2. Is photonic Bandgap dependent on number of valence electrons, in anyway?
3. Tungsten: 5d46s2, Chromium: 3d54s1, Molybdenum: 3d54s1, does the availability of valence electrons at different shell levels going to effect the spectral emissivity? e.g. in Tungsten(W) the 5d has 4 and 6s has 2, they offer 6 valence electrons in all. where as, chromium 3d has 5 and 4s has 1.Molybdenum: 3d has 5 and 4s has 1 to offer. Nnow would that also mean since Mo and Cr's d and s are offering similar electrons, so the properties would also be strikingly similar as compared to Tungsten?
4. Is photonic Bandgap also dependent on valence electrons available at different shells?
Thanks for your replies.
