Metal-insulator-metal transition induced by a uniaxial strain in a gapless semiconductor Hg1-xCdxTe

A metal-insulator-metal transition is shown to occur in a uniaxially strained gapless semiconductor H1 _xCdxTe. In the absence of a strain, the metallic conductivity is determined by the free electrons and when Ρ is maximum, it is determined by the valence-band holes. A conductivity inversion is caused by a structural change in the hole spectrum.
