Sige strain thermal
WebDec 20, 2013 · SiGe epitaxial layers are integrated as an active part in thermal detectors. To improve their performance, deeper understanding of design parameters, such as thickness, well periodicity, quality, and strain amount, of the layers/interfaces is required. Oxygen (2–2500 × 10−9 Torr) was exposed prior or during epitaxy of SiGe/Si multilayers. WebFeb 10, 2024 · The results of the material flow velocities, strain, and temperatures were shown and connected to the experimental findings. Xiaong et al. developed an axisymmetric 2D model to simulate refill FSSW of AA7075-T6 in ForgeNxt3.2 software. The model was validated based on thermal results, and void formation was correlated to material flow.
