Paper Abstract

Magnetoresistance of long correlated nanowires of degenerate semiconductor InSb in asbestos matrix (wire diameter is around 50 Å, length 0.1 - 1 mm) is studied over temperature range 2.3 - 300 K. At zero magnetic field the electric conduction G and current-voltage characteristics of such wires obeys the power laws G varies direct as Tα, I varies direct as Vβ, expected for one-dimensional electron systems. The effect of magnetic field corresponds to 20% growth of the exponents α, β at H = 10 T that may result from breaking of the spin-charge separation in the one-dimensional electron system.
