Graphite changes to hexagonal diamond in picoseconds

Aug. 8, 2022 - 
The graphite-diamond phase transition is of particular interest for fundamental reasons and a wide range of applications. On very fast compression time scales, material kinetics hinder the transition from graphite to the equilibrium cubic diamond crystal structure that we commonly know as diamond. Shock wave compression of graphite typically requires pressures above 50 GPa (500,000...
