Electroless Contact Study on CdTe Nuclear Detectors: New Results and Element Deposition

Electroless deposited contacts are frequently used for II-VI semiconductor materials and particularly on CdTe/CdZnTe. This chemical deposition method creates a stronger chemical bond and few nested interfacial layers between the contact and the semiconductor when compared to physical deposition methods such as sputtering or evaporation. This method also forms a moderate quasi-ohmic contact which eliminates the spectral degradation problem caused by the polarization effect.
