The most important challenge is to identify the size and material of defect particles that are found.
The material of the defect and the shape can be extracted by calculate the DSCS, which provide strong theoretical foundation to the nondestructive detector engineer.
Therefore, the dent position and material can be inversed and decided by calculating the particle DSCS.

Its absorption region consists of 20×Si1-xGex/Si quantum wells instead of Si or Ge bulk materials.
Unlike GaAs-based materials, epitaxiial SiGe/Si layers cannot be used as the distributed Bragg reflector (DBR) because of small difference of refractive index and large lattice mismatch between Si and Ge.

It is represented with -3σ, b, a, or s basis of material performance according to mechanical properties data representation standards.
However, it is difficult to precisely characterize the product cushioning suitability, for these methods are value design methods and ignore environmental conditions, material properties, cushion geometric parameters, the stochastic nature of the fragility and other design parameters.
