Continuum lowering
WebMar 18, 2024 · This phenomenon, called ‘continuum lowering,’ is important in the high-energy density (HED) regime. To understand the relative contributions of pressure and temperature, we used density-functional theory to study diamond silicon at low temperature but under extreme pressure, up to 150 Mbar and 12× density.
