Abstract

We observed non-classical contributions to the conductivity in three-dimensional samples at temperatures up to 35 K. The experiments were carried out inn-type Hg0.8Cd0.2Te samples having dimensions as large as 8 ×28×25 μm3. The two resistivity contributions, i.e. the ‘normal’ metallic behaviourρ 0 and a partΔρ provided by electron interference, are separated using a method disturbing the additional contribution by heating the electrons in electrical fields. The observed temperature and electric field dependence are compared with existing theories.
