Klaus von Klitzing,德国物理学家,1943年生.他在1980年研究二维电子气在强磁场中的输运性质时发现了霍尔电阻高度精确的量子化效应.这一发现为他赢得了1985年的诺贝尔物理学奖.国际计量标准化组织在1990年决定使用量子霍尔电阻(RK=h/e2=25812.807欧姆)作为电阻的国际标准,并用他的名字命名.他的发现的重要性还在于量子霍尔电阻的精确性与普适性引发了规范不变性、几何相位和拓扑不变量等重要理论概
Klaus von Klitzing, German physicist, born in 1943. He discovered the highly accurate quantum effect of Hall resistance when he studied the transport properties of two-dimensional electron gas in a strong magnetic field in 1980. This finding won him 1985 Nobel Prize in Physics in 1990. The International Organization for Standardization in 1990 decided to use the quantum Hall resistance (RK = h / e2 = 25812.807 ohms) as an international standard resistance and named after him. The importance of his discovery also The accuracy and universality of quantum Hall resistors have led to the introduction of important theories such as invariability of the norms, geometric phases and topological invariants
