Reason for change in deformation if we switch from n to p

[Ganga Raju]

In the research paper, a piezoresistive pressure sensor is designed.
My question is if we look at table 1
in column 1 the values of deformation of diaphragm for single crystal silicon n type is used
If we interchange n type and p type the values for 1000,2000 Kpa are same and then the values changes, why ?
and why n,p type is not getting any deformation after 3000 Kpa ?

The values of deformation for single crystal silicon n type and p type remain the same up to 3000 KPa because both materials have similar mechanical properties. As the pressure increases, the differences in the mechanical properties of the two types of silicon start to become more pronounced, leading to different levels of deformation at higher pressures. This difference is most likely due to the different crystal structures of n-type and p-type silicon, which affects their ability to resist deformation. Additionally, the threshold values of 3000 KPa might indicate that the sensor has reached its maximum capacity, meaning that further increases in pressure will not cause any additional deformation.
