Comments on "Ohm's Law Survives to the Atomic Scale" by Weber et al

Abstract

The recent article "Ohm's Law Survives to the Atomic Scale" by Weber et al. [Science 335, 64 (1021)] reveals ohmic transport in quantized P-in-Si wires. We argue that their results have two main deficiencies: (a) the interpretation of conductance data is inadequate for serious systematics; (b) metallic-like structures hold few implications for quantum computing.Comment: 2pp; see http://comments.sciencemag.org/content/10.1126/science.121431
