The zero-bias anomaly in the tunnel conductance G(V, H) characteristics of Pb-Si0...-InSb junctions was investigated under zero and 37.2 k0e magnetic fields at4.4 K for the junction fabricated on n-InSb (n = 8.14 X 10" cm ') and under magneticfields from 0 to 31.0k0e at 4.2K for the junction fabricated on p-InSb (p2.65 X 10" cm '). The G(V, H) was almost independent of the magnetic field for thejunction fabricated on n-InSb. For the junction fabricated on p-InSb, the magneticfield dependence of differential resistance 7?(0, H) = l / 640, H) was found to obey therelation In 7<(0, H)cf-H. Taking into account the shrinkage of hole orbit in localizedstates with the magnetic field, we can explain the behavior by the variable-range hop-ping assisted tunneling.
