CdTe nanowires were prepared by electrochemical deposition in nanoporous polycarbonate membranes. The method offers some very important degrees of freedom, i.e. the possibility to choose the desired density of nanopores by selecting the appropriate heavy ion irradiation fluence and the desired size and shape of the nanopores by using the appropriate etching conditions. Thus one can employ templates with the desired characteristics: high pore density for measurements of optical, structural or morphological characteristics of the nanowires and low pore density membranes for transport characterization.

The present report deals with the influence of the preparation conditions on the properties of CdTe nanowires. Thus the influence of parameters such as deposition potential or temperature on morphological or structural properties were investigated. Moreover, differences between wires deposited at constant potential and in a pulsed regime were emphasized.

Transport properties were also investigated, special attention being paid to metal semiconductor contacts properties at nanoscale.
