Introduction Silicon-based photodetectors are the devices that convert optical signals into electrical signals, and they have unique advantages compared with the systems based on other materials because of the semiconductor material silicon, as the leading photoelectric materials, which have abundant resources, low cost, environment-friendly, mature processing technology and other outstanding properties [1,2].
Common traditional semiconductor materials include cadmium sulfide (CdS) [3], lead sulfide (PbS) [4], indium antimonide (InSb) [5,6], indium arsenide (InAs) [7], mercury telluride (HgCdTe) [8], etc.

Its heterogeneity is caused mainly by the assembly of two materials with different material characteristics.
Masonry unit and mortar themselves are considered as heterogeneous materials.
Many real materials have a larger Mohr-Coulomb friction angle than this value.
The numerical simulation have been made under the assumption of four different materials model.
