3D phonon stability boundaries

Caption

An international team of scientists discovered using supercomputer simulations that by flexing diamond, its thermal conductivity can be drastically tuned up or down. The stability boundaries for the ε23–ε13–ε12 shear strain subspace shown colored by h. The regions in light green, blue, red/crimson correspond to 𝑘c of the “Δ”, “L”, “Γ” types, respectively.
