piezoelektřina --- elektrický odpor

This thesis is devoted to a piezoelectric and dielectric studies of ferroelectric semiconductors of Sn2P2(SexS1-x)6 crystal family and their phase transitions due to an interesting physical properties and strong piezoelectric and pyroelectric effect. For further measurements crystals with different concentration of selenium were used. A special study is devoted to a frequency, temperature and pressure investigations of the dielectric and piezoelectric properties, also the electrical resistance measurements and their behavior in the vicinity of the phase transition point.
