摘要:

单极开关现象近年来引起了广泛的关注,但开关电压的广泛分布仍然对科学进步和实际应用构成了主要障碍。使用NiO电容器,我们研究了电容电压和电流的分布。我们发现,他们缩放的电阻值Ro在低电阻状态,和缩放指数在Ro = 30欧姆变化。我们解释这些有趣的标度行为和他们的交叉类比与逾渗理论。我们表明,导电丝的连接起着至关重要的作用,在超导过程中。

英文摘要:

Unipolar switching phenomena have attracted a great deal of recent attention, but the wide distributions of switching voltages still pose major obstacles for scientific advancement and practical applications. Using NiO capacitors, we investigated the distributions of the RESET voltage and current. We found that they scaled with the resistance value Ro in the low resistance state, and that the scaling exponents varied at Ro = 30 Ohm. We explain these intriguing scaling behaviors and their crossovers by analogy with percolation theory. We show that the connectivity of conducting filaments plays a crucial role in the RESET process.
