Abstract
Recent experimental results are consistent with the prediction that superconductivity is suppressed in aluminum nanoparticles which are so small (∼10 nm diameter) that the electronic energy level spacing exceeds the superconducting energy gap in bulk material. Very recent experiments on nanowires (diameter ∼5–10 nm, length ∼150 nm) of MoGe indicate that a dissipative phase transition between superconducting and normal behavior occurs when the normal resistance of the wire equals the superconducting quantum resistance h/4e^2 ≈ 6.5 kΩ.
