摘要：

Resistance measurements were made on high-resistivity thin-film metal strips at temperatures as low as 10 mK. Unexpected logarithmic variations of the resistance with temperature and applied electric field were observed for strips with sheet resistance below R□∼10 kΩ/□ and widths 1 μm. Exponential increases in resistance were observed for similar films when the film width was decreased to about 0.1 μm or when R□ was increased to ∼ 10 kΩ/□. © 1979 The American Physical Society.
