Q: What does it mean if the Fermi level crosses into the valence band? How about into the conduction band?

tumblewushI've been working on this material to get more accustomed to Quantum Espresso, and I've gone on and performed calculations to get their band structures. Here are the band structures that I got for two of the variations of my material: Used EV-GGA to get these band structures, I could have used o...

Q: Why doesn't a nucleus-like body made up of just neutrons exist?

MehulWe know that neutrons exert short ranged nuclear forces over other nucleons in a nucleus, and these forces are only attractive in nature.
