WebJul 25, 2024 · As the pressure increased, the band gap initially began to red shift before 1.0 GPa followed by a continuous blue shift until the crystal was completely amorphized. An isostructural phase transition at 1.2 GPa was determined by high-pressure synchrotron X-ray and Raman spectroscopy. WebApr 27, 2011 · Molecular phase III ( P 2 1 / c) is one such; it remains metastable to higher pressures up to ∼200 GPa, at which point it too rearranges spontaneously to a saturated, tetracoordinate CH polymer. At 300 K the isomerization transition occurs at …
