AlN:Er薄膜在不同退火温度下应力诱导的微观结构演变
Stress Induced Microstructure Evolution of AlN: Er Film at Different Annealing Temperature
摘要
Abstract
The microstructure evolution of AlN: Er during thermal treatment was mainly characterized by weak beam diffraction-contrast imaging and high resolution phase-contrast imaging of the transmission electron micros-copy (TEM), which was also supported by X-ray diffraction (XRD) and Raman spectroscopy. Three regions could be observed in the TEM for the implanted samples. The region Ⅰ is about 30 nm in depth below the surface, the re-gion Ⅱ is about 50 nm in depth under the region I and is the worst damaged area, and the region Ⅲ is the area below the reigion Ⅱ. At relatively low annealing temperature, such as 1025℃, the regionI disappears. However, this area can be observed again after annealing at 1200℃.Based on the results of XRD, Raman and TEM, the interesting experiment phenomenon are explained on the view of damage recovery and stress releasing. There is a large stress in the region Ⅱ due to the large radius difference between Er ions and Ga ions. In the annealing process at 1025℃, the region Ⅰ is affected by the stress from region Ⅱ, the lattice distortion in region Ⅰ is produced. Therefore, the re-gion Ⅰ is observed as region Ⅱ under TEM observation. In the annealing process at 1200℃, the stress in the region Ⅰ is released from the surface, the lattice distortion is removed and the region Ⅰ is observed again under TEM.关键词
