图1: 非局域电输运测量探测在近邻效应诱导的金纳米线超导转变温度处出现的奇异电压峰 (IMAGE) Science China Press Caption 非局域电输运测量探测在近邻效应诱导的金纳米线超导转变温度处出现的奇异电压峰。当温度下降跨越超导转变温度时,信号为电压峰。反之,为电压谷。上插图:金纳米线的扫描电镜(SEM)图像,两侧为非超导的Pt电极,中间为超导的W电极。下插图:输入电流和探测电压的示意图。事实上,所测的电压与输入的电流无关,输入电流为零时,依然可以观测到同样的现象。 Credit ©《中国科学》杂志社 Usage Restrictions None License Licensed content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
