Weak localization and interaction in doped CdTe

We study weak localization and electron interaction in CdTe:In by low tempe rature 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 magnet ic field and probably induced by the proximity of the superconducting conta ct.
