The present article is a review of our experimental works performed on PbTe nanostructures. An uniqueness of lead telluride relies on combination of excellent semiconducting properties, like high electron mobility and tunable carrier concentration, with paraelectric behavior leading to huge dielectric constant at low temperatures. For nanostructured constrictions of PbTe we have observed 1-dimensional quantization of electron motion at much more impure conditions than in any other system studied so far. This is possible due to dielectric screening of Coulomb potential fluctuations produced by various defects usually existing in the solid state environment. In an external magnetic field, the quantization shows very pronounced spin splitting, already discernible at several kilogauss. This indicates that PbTe nanostructures are very promising as local spin-filtering devices.
