H atoms were loaded to a Pd film in H2 gas pressure of ∼0.25 MPa at temperatures of T = 180 and 150 K. At T = 180 K, after the resistivity variation due to H absorption was almost stopped, the PdHx film was cooled rapidly to low temperatures for the resistivity measurements. A superconducting transition was observed at Tc ∼ 1.1 K, where the transition width is smaller than 0.1 K. This indicates that a high-quality sample with a sharp transition can be obtained by providing sufficient time for H absorption. At T = 150 K, although the resistivity variation remained, the film was cooled. The transition temperature Tc increased to ∼2.1 K, whereas the transition width increased owing to the inhomogeneity of the H concentration in the film. Curiously, regardless of the H homogeneity, there remained a similar T-dependent residual resistivity in both films prepared at T = 180 and 150 K after the superconducting transition. This implies that the observed residual resistivity is essential for the future of the system, although its origin is not clear.","PeriodicalId":17304,"journal":{"name":"Journal of the Physical Society of Japan","volume":"81 3 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139422832","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Takada et al., Phys. Rev. Lett. 113, 126601 (2014)]. The wires are partly tunnel-coupled to each other to form a mesoscopic ring with an embedded quantum dot. Our method consists of two stages. In the first stage, we represent the experimental system with a tight-binding model by discretizing the space. The conductance around a Coulomb peak is evaluated as a function of magnetic field in four-terminal geometry, where the Coulomb interaction is irrelevant. We show clear Aharonov–Bohm (AB) oscillations despite the multiple conduction channels and magnetic field inside the wires. In the second stage, we adopt a model of double quantum dot (DQD) in parallel. The model parameters are chosen to reproduce the Coulomb peak and AB oscillations obtained in the first stage in the absence of the Coulomb interaction U. Finally, we calculate the conductance in the Kondo valley using the DQD model in the presence of U. We observe phase locking at π/2, which is consistent with experimental results.","PeriodicalId":17304,"journal":{"name":"Journal of the Physical Society of Japan","volume":"266 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139421342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we report on the single crystal growth, bulk transport properties, and band structure calculations of these compounds. The magnetotransport properties indicate that all three compounds are multi-carrier systems. The experimental results of ZrTiTe4 and HfTiTe4 can be well fitted by the multi-carrier formula assuming two types of carriers, while three carrier components were necessary for HfZrTe4. Interestingly, one of the carrier mobilities of HfZrTe4 exceeded 1000 cm2 V−1 s−1, which was nearly one order in magnitude larger than the carrier mobilities of ZrTiTe4 and HfTiTe4. Our band structure calculations showed that all three compounds are semimetals consistent with the magnetotransport properties. The band structure around the Γ-point of HfZrTe4 exhibits features that are distinct from the other two compounds, which is likely the reason of the different carrier properties.","PeriodicalId":17304,"journal":{"name":"Journal of the Physical Society of Japan","volume":"29 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138746051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
