                         junctions grown on 111 BaF2 substrates, in which the hole 
                         concentration p was kept constant at 1017 cm\−3 and the 
                         electron concentration n varied between 1017 and 1019 
                         cm\−3. Capacitance-voltage analysis showed that for n1018 
                         cm\−3 the PbTe p-n junction is one sided and abrupt. The 
                         parameters incremental resistance, series and parallel 
                         resistances, and ideality factor obtained from the current-voltage 
                         I-V characteristics and the detectivity D* exhibited a large 
                         fluctuation among the photodiodes. In spite of these fluctuations, 
                         it was possible to correlate the noise and D* values to the 
                         parameters obtained from the I-V analysis. These results allow 
                         predicting the PbTe detectors figures of merit from the data 
                         obtained from the I-V curves. The best PbTe photodiodes fabricated 
                         here showed D* values close to 1011 cm Hz1/2 W\−1, 
                         comparable to InSb and HgCdTe commercial detectors and to PbTe
