Two compositions have been described: Pb,H,TeO,, obtained by the interaction between H,TeO, and Pb(CH,COO), [l], and 3PbO - 2Te0, - 2HZ0, which was synthesized by the interaction between Pb(NO,), and K,H,TeO,, the latter being dissolved in such a quantity of KOH that the ...
We carried out high-pressure resistivity and Hall-effect measurements in single crystals of CdTe and ZnTe up to 12 Gpa. Slight changes in transport parameters in the zinc-blende phase of CdTe are consistent with the shallow character of donor impurities. Drastic changes in all the transport param...
