Congruent Melting of GaN at High Pressures
Gallium nitride (GaN) is a very important material in optoelectronic devices for blue light-emitting diodes and lasers [1]. These devices are usually fabricated by epitaxial growth on sapphire (Al 2O3) substrates because larg e GaN single crystals are unavailable. There is a large mismatch in the lattice constants of sapphire and GaN, which causes high-density dislocations in the deposited laye...
متن کاملMelting of Tin at High Pressures
Introduction Information about the physical properties of materials at high pressures and temperatures is important for advancing our understanding of planetary interiors. Determining the melting curves of materials has attracted much interest in the planetary sciences. For example, the pressure dependencies of the melting curve and viscosity have been linked [1]. Furthermore, the accurate dete...
متن کاملPredicted reentrant melting of dense hydrogen at ultra-high pressures
The phase diagram of hydrogen is one of the most important challenges in high-pressure physics and astrophysics. Especially, the melting of dense hydrogen is complicated by dimer dissociation, metallization and nuclear quantum effect of protons, which together lead to a cold melting of dense hydrogen when above 500 GPa. Nonetheless, the variation of the melting curve at higher pressures is virt...
متن کاملMicrostructures define melting of molybdenum at high pressures
High-pressure melting anchors the phase diagram of a material, revealing the effect of pressure on the breakdown of the ordering of atoms in the solid. An important case is molybdenum, which has long been speculated to undergo an exceptionally steep increase in melting temperature when compressed. On the other hand, previous experiments showed nearly constant melting temperature as a function o...
متن کاملAnomalous melting behavior of solid hydrogen at high pressures
Hydrogen is the most abundant element in the universe, and its properties under conditions of high temperature and pressure are crucial to understand the interior of large gaseous planets and other astrophysical bodies. At ultra-high pressures solid hydrogen has been predicted to transform into a quantum fluid, because of its high zero-point motion. Here we report first-principles twophase coex...
