Single crystal mat (SCM) samples of polyethylene (PE) were prepared from dilute solution of p-xylen, then they were annealed at pressures of 200 and 500 MPa. Lamellar thickness of the original and annealed SCM samples was measured by smallangle X-ray scattering method. Orientation of the molecular c
We have performed band structure calculations of high pressure phases of phosphorus within the local-density-functional formalism and the norm-conserving pseudopotential method. The structural stability of the simple hexagonal phase of phosphorus has been studied, and the calculated transition press
