"When most, but not all, layers had switched to prismatic state, the sample was cooled back to room temperature... layers that remained in the octahedral state were exhibiting charge density waves that were orderly and stable, and stayed that way at temperatures of up to 170 F. In addition, those layers had flipped from semiconductors to insulators"
