There are a lot of studies on the essence and the connotation of product design, the representative one is the research from philosophy or cognitive science.
Firstly, product design is a brain-based thinking activity because the brain is the material foundation for thinking.

Stress distributions and their generation mechanisms in a hetero-epitaxy SOS thin film system are complicated because of the single crystal anisotropy of the materials, their differences in thermal expansion properties and lattice mismatch.
Hughes [4] theoretically estimated the residual stress induced by differences of thermal expansion coefficients between silicon and sapphire materials, and correlated it with the piezoresistanceeffects.
However, in single crystal materials, the measuring directions are limited by the crystallographic orientations of (h k l) planes that can contribute to diffraction; thus 3-axes sample alignments are required to adjust the measured (hkl) plane in the most exact diffraction condition.

Moreno-Armenta et al. [4] has explained that copper nitride is an indirect semiconducting material with a band gap close to 0.25 eV.
X-ray diffraction measurements indicate that all these materials are composed of copper nitride crystallites with anti-ReO3 structure, which exhibiting preferential orientation of the (111) direction and the crystal growth of the Mn-doped copper nitride films were influenced heavily by manganese elements.
