Weak localization and interaction in doped CdTe

Abstract:

We study weak localization and electron interaction in CdTe:In by low temperature magnetoconductance experiments to quantify the phase breaking length and the importance of interactions in CdTe. Then we study superconducting contacts to CdTe:In by transport measurements at very low temperature. The conductance-voltage characteristics of the superconducting contact exhibits the main features of a SIN junction, with a superimposed zero bias anomaly. This anomaly in the density of states of CdTe is very sensitive to magnetic field and probably induced by the proximity of the superconducting contact.
