He was a professor and research scientist at Columbia University and the University of Chicago.The first thing they note is that the Fermi Paradox is a remarkably strong argument. You can quibble about the speed of alien spacecraft, whether it’s 1% the speed of light or 10% the speed of light. It doesn’t matter. You can argue about how long it would take for a new star colony to spawn colonies of its own. It still doesn’t matter.Gamma-ray Burst Monitor (GBM) The GBM includes two sets of detectors: twelve sodium iodide (NaI) scintillators, each 12.7 cm in diameter by 1.27 cm thick, and two cylindrical bismuth germanate (BGO) scintillators, each 12.7 cm in diameter and 12.7 cm in height.

In fact, by controlling the doping, it can be made it as close to the band edge as we want. On the other hand, in metal, where the conduction band is partially filled with electrons, the Fermi energy is necessarily quite big.
