The gauge factor decreases quickly as doping concentration exceeds 1019 cm−3. However, one advantage of polysilicon over crystalline silicon is its reduced TCR. 14% per degree Celsius for crystalline silicon. The deposition process and the dopant species have been found to even alter the sign of the TCR. 045% per degree Celsius. Resistors with positive TCR are particularly useful in compensating the negative temperature dependence of piezoresistive sensors. Piezoelectricity Certain classes of crystals exhibit the peculiar property of producing an electric field when subjected to an external force.

The piezoelectric effect is described in terms of piezoelectric charge coefficients, dij, which relate the static voltage, electric field, or surface charge in the i direction to displacement, applied force, or stress in the j direction. The convention for describing piezoelectrics is that the direction of polarization is the “3” or z direction of the crystal axis, while a direction perpendicular to it is the “1” or x or y direction of the crystal. 5 Illustration of the piezoelectric effect in a hypothetical two-dimensional crystal.
