## Abstract AlN doped SiC films were deposited on onβaxis Siβface 4HβSiC (0001) substrates by the physical vapor transport (PVT) method. Thick film in the range of 20 ΞΌm range was grown and morphology was characterized. Films were grown by physical vapor deposition (PVD) in a vertical geometry in t

## Abstract The growth of AlN crystals by PVT method was investigated using TaC crucible in the temperature range of 2250β2350 Β°C. AlN boules with 30 mm in diameter were successfully grown on the crucible lid by selfβseeded growth. The AlN boules consist of the spontaneously nucleated AlN single cr
Aluminum nitride (AlN) single crystals, approximately 25 mm in diameter and up to 15 mm thickness, were grown by the physical vapor transport (PVT) method in tungsten crucibles. To study the effect of growth direction and polarity, growth was performed using AlN seeds of very different orientations,
