The forward current-voltage (I-V) characteristics of the n+-p silicon diodes, B-doped with impurity density p=2.1017 cm-3 and P-doped with impurity density n=2.1020 cm-3, have been investigated in the temperature range from 4.2 K to 293 K. The peculiarities of the low-temperature conductivity of diodes have been studied by the novel differential technique of experimental results treatment. The ranges of power-like and exponential dependencies of the I-V curves have been determined. Different physical mechanisms responsible for the formation of peculiarities of the low-temperature I-V characteristics have briefly been discussed.
