The δE for different fields in the absorption layer with different γ. The values of γ is 1.0 (black star), 1.1 (black down-pointing triangle), 1.2 (black diamond), 1.3 (black triangle), 1.4 (black square), 1.5(black circle). Presents the calculated results of δE by Formula 16. When the field of absorption exceeds 19 kV/cm, δE gradually increases. It also can be found that δE adapts the same order of magnitude for the avalanche field in the multiplication. Thus, the tunneling effect has an influence on the avalanche field with the tunneling effect
