Great to see this discussion. My son displayed a science project on negative differential resistance 21 years ago. Had quite a few electrical engineers passing by with "the low brow" look. His device involved carbon fibers arranged in a cross shape placed inside of a cement mixture and compressed to ~8,000 psi during the cure stage (following the example of some published research).
