After the assessment of material reorganization after annealing, the crystallographic structure of the closed pores surface is investigated.
Careful examination suggests that the superficial layer on the inner pore wall may not follow the same ordered crystalline structure as expected from the bulk material.

Part of them is due to the impurities of source material [6], indicating that the purity of source powder needed to be enhanced.
Experiment High purity silicon (99.999%) and carbon (99.999%) powder was selected as starting materials.

Fig.2 New scheme of the sensor The sensor also contains two layers, the nonconductive isolated layer, which is used to insulate the substrate and the sensing layer, which is made of conductive materials[3].
Because the coating technics in prepare sensing layer is thermal spraying, which is just the same as in reference [2], the coating is an isotropic material, and the resistivity is 0.085Ω•m.
