A Experimental Semiconductor Bandgap Databases

Click For Summary
Experimental bandgap information is sought for comparison with DFT calculations from the Materials Project and OQMD. Users are looking for extensive datasets beyond the basic lists available on Wikipedia. The CRC Handbook of Chemistry and Physics is recommended as a reliable source for this data. The discussion emphasizes the need for comprehensive databases to facilitate accurate comparisons. Accessing detailed experimental data is crucial for validating computational models in semiconductor research.

What are the best databases of experimental semiconductor bandgaps?
I'm looking for experimental bandgap information to compare it to DFT calculations from Materials Project and OQMD. Could anyone recommend some?

For experimental bandgap information, you probably can rely on the CRC Handbook of Chemistry and Physics.
 
From the BCS theory of superconductivity is well known that the superfluid density smoothly decreases with increasing temperature. Annihilated superfluid carriers become normal and lose their momenta on lattice atoms. So if we induce a persistent supercurrent in a ring below Tc and after that slowly increase the temperature, we must observe a decrease in the actual supercurrent, because the density of electron pairs and total supercurrent momentum decrease. However, this supercurrent...
