1. A material is tested at 1 atmosphere and found to be an insulator. It is then very strongly compressed and found to have very much increased conductivity. Speculate on what changes may be happening to the energy band structure of the material.© BrainMass Inc. brainmass.com June 3, 2020, 7:18 pm ad1c9bdddf
Please see the answer to your question in the attached word file ...
It explains the energy band structure of the material so that the conductivity increases at it being cmpressed.
