Abstract Quantum conductance corrections (QCCs) due to weak localization and interaction effects of quantum quasiballistic wires are investigated for the first time. At temperatures in the range 2 K〈T〈12 K a crossover of these corrections from one-dimensional behavior to zero-dimensional behavior is observed. It is shown that the phase coherence length in the wires studied is less than the length L T =(ℏD/kT)1/2 at all temperatures. It is found that the conventional theory of QCCs describes correctly the experimental temperature dependence of the QCCs but gives a much lower value than the experimental one.
