| 摘 要： | Self-seeded aluminium nitride （AlN） crystals are grown in tungsten and hot pressed boron nitride （HPBN） crucibles with different shapes by a sublimation method. The qualities of the AlN crystals are characterized by high-resolution transmission electronic microscopy （HRTEM）, scanning electron microscopy （SEM） and Micro-Rarnan spectroscopy. The results indicate that the better quality crystals can be collected in conical tungsten crucible.
