摘要

我们展示了一种基于 MgB2 的微波动感探测器（MKID），其在 2 K 时的品质因数为 Qi ~ 105，噪声等效功率 NEP ~ 10-14 W/Hz。与基于 YBCO 的 MKID 相比，MgB2 探测器对温度和磁场的灵敏度更高，这是其双间隙性质和相对较低的临界 Hc2 场的结果。我们的数据表明，MgB2 在温度低于 3 K 的 MKID 应用中更具优势。

Microwave Kinetic Inductance Detector Made of Molecular Beam Epitaxy (MBE)-Grown MgB2 Film.

We present a MgB₂-based Microwave Kinetic Inductance Detector (MKID) featuring a quality factor Q_i ~ 10⁵ and noise equivalent power NEP ~ 10^-14 W/Hz at 2 K. In comparison to YBCO-based MKIDs, the MgB₂ detector shows greater sensitivity to both temperature and magnetic field, a result of its two-gap nature and relatively low critical Hc2 field. Our data indicate that MgB₂ is more advantageous for MKID applications at temperatures lower than 3 K.

期刊介绍： Nanomaterials (ISSN 2076-4991) is an international and interdisciplinary scholarly open access journal. It publishes reviews, regular research papers, communications, and short notes that are relevant to any field of study that involves nanomaterials, with respect to their science and application. Thus, theoretical and experimental articles will be accepted, along with articles that deal with the synthesis and use of nanomaterials. Articles that synthesize information from multiple fields, and which place discoveries within a broader context, will be preferred. There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental or methodical details, or both, must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Nanomaterials is dedicated to a high scientific standard. All manuscripts undergo a rigorous reviewing process and decisions are based on the recommendations of independent reviewers.
