摘要
For the first time a direct proof of ferroelectric behavior in strong doped lead tin telluride is given. The structural phase transition from paraelectric to ferroelectric phase is also seen in galvanomagnetic and photoelectric properties. An explanation of the observed properties is given by connecting the local Jahn-Teller reconstruction of the lattice around defects with structural phase transition.
