Piezo-Resistance and Piezo-Hall Effect in Bismuth

IBM Journal of Research and Development, 1964
The electrical resistivity and Hall coefficient in single crystals of bismuth have been measured as a function of uniaxial stress along the trigonal axis at 4.2°, 77°, and 295°K. The data are analyzed in terms of a two band model to determine the deformation potential components E 1 and E 2 given by δE 0 = E 1 (e 11 + e 22 )+ E 2 e 33 , where E 0 ...

Piezo- and Pyroelectric Properties

1980
Some polymers can be made both piezo- and pyroelectric by suitable application of a large electric field. This effect is true piezo- and pyroelectricity rather than electrostriction, conduction, electromechanical effects, or the motion of conductors in the field of space charges. Two distinct types of polymers can be piezoelectric.
