Tunneling conductance in quantum-wire/insulator/unconventional superconductor (q/I/S) junctions is calculated in the case where the unconventional superconductor has triplet symmetry. Differently from the case in d-wave superconductor junctions, the magnitude of the tunneling conductance near zero voltage is enhanced due to the Andreev bound state by the quasiparticle with perpendicular injection. From the tunneling spectroscopy of q/I/S junctions, we can distinguish p-wave (triplet) superconductor from d-wave (singlet) one. (C) 2001 Published by Elsevier Science BY. [References: 23]
