Title :無冷媒14 T 超伝導磁石内蔵1.5 K クライオスタットの導入と電気抵抗標準の実測
Authors :鈴木 恭一
Issue Date :23-Apr-2020
Abstract :We introduced a liquid helium-free cryostat for studying quantum mechanical electron transports in semiconductors or topological insulators. This cryostat can cool the samples down to 1.5 K and is equipped with 14 T superconducting magnet. The resistance standard originating from the conductance quantization was accurately measured by the quantum Hall effect measurement in a Si-modulation-doped AlGaAs/GaAs single heterostructure, in which high-mobility two-dimensional electron channel was formed. In addition, diamagnetic levitation of bismuth was successively observed. Further enhancement of our study is expected using this cryostat system.
