Formation and Structure of Melt from Solids with Highly Symmetrical Packing Arrangements |
Jozsef GaraiAbstractThe interatomic potential energies of the neighboring atoms overlap; therefore, in a crystalline solid above a certain energy level a uniform metastable state develops. In this state, atoms, atomic lines, and atomic sheets can be displaced vibrationally. Energy and geometrical considerations indicate that metastable double atomic sheets should develop when melting occurs in highly symmetrical packing arrangements. Previous x-ray and neutron diffraction investigations of liquids show that the observed diffraction peaks are consistent with the predicted interlayer separations of these double sheets.
