However, the previously reported Ge<sub>1-<em>x</em></sub>Mn<sub><em>x</em></sub>Te alloys with low MnTe content may mix with the rhombohedral phase of GeTe, making the sample unstable during thermal cycling. Moreover, the exact phase of GeTe-MnTe-based alloys have not been thoroughly studied. In this work, a series of Ge<sub>1-<em>x</em></sub>Mn<sub><em>x</em></sub>Te (0 ≤ <em>x</em> ≤ 1) compounds were synthesized, and the changes in crystal structure and thermoelectric properties were investigated across the composition range from GeTe to MnTe. At the phase boundary, both rhombohedral and cubic phases GeTe coexist in the range of <em>x</em> = 0.15 to 0.3, while cubic phase GeTe and hexagonal MnTe phases coexist for <em>x</em> = 0.5 to 0.7. The single cubic phase is observed only near <em>x</em> = 0.4. Alloying with MnTe significantly increase the effective mass of the electronic band, which negatively impacts the electrical performance, suggesting that the thermoelectric properties are compromised in favor of enhancing the stability of the GeTe structure. Although the resistivity of the alloy increases with Mn content, the Seebeck coefficient rises significantly, and thermal conductivity decreases. These changes are likely due to enhanced phonon scattering caused by the two phases and the Mn solute atoms. As a result, relatively high figure-of-merit (<em>zT</em>) values are achieved in the rhombohedral-to-cubic phase transition region (<em>x</em> = 0.15, 0.2, 0.3) for Ge<sub>1-<em>x</em></sub>Mn<sub><em>x</em></sub>Te.</div></div>","PeriodicalId":18253,"journal":{"name":"Materials Today Physics","volume":"51 ","pages":"Article 101661"},"PeriodicalIF":10.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143030805","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, the PHE of single crystal intrinsic ferromagnetic topological insulator MnBi<sub>8</sub>Te<sub>13</sub> is studied in detail for the first time.

Anisotropic magnetoresistance (AMR) measurements show that the sign reversal of resistivity can be attributed to the different dependence of resistivity on the magnetic field when the field is parallel and perpendicular to the current direction. Further analysis of the PHE and AMR data has demonstrated that the anisotropic magnetoresistance, rather than the chiral anomaly, plays a dominant role in the PHE of MnBi<sub>8</sub>Te<sub>13</sub>.

However, the structure-function black box limits the design and preparation of microwave-absorbing materials through traditional trial and error methods, characterized by a time-consuming cycle between microscopic material modification and macroscopic performance measurement. Here, we present a novel machine learning-based approach to predict electromagnetic parameters of materials with excellent microwave absorption properties. Through introducing air, a “five-layer” films structure, composed of lamellar MXene, hollow spherical MXene, lamellar MXene, hollow spherical MXene, and lamellar MXene, is designed, which exhibit greatly enhanced the microwave absorption performance compared with pure layered MXene films. Our results demonstrate that the precise tuning of the electromagnetic parameters and the moderate improvement of the impedance matching achieves within this composite, greatly enhancing the dielectric loss capability of the films. Owing to the microstructural characteristics, the films shows the minimum reflection loss (RL<sub>min</sub>) of −48.15 dB and the maximum effective absorption bandwidth (EAB<sub>max</sub>) of 5.84 GHz.

In this study, we present experimental measurements on mesoporous silica and atomistic analyses using Monte Carlo simulations and machine learning models to quantify the relationship between nanoarchitecture and effective thermal conductivity. Through rational chemical synthesis and ultrafast spectroscopy measurements, a strong size dependence within the sub-10 nm regime is observed, where the classical Fourier heat conduction theory fails to account for the effects of porosity and pore size. This deviation from diffusive transport is attributed to the significant contribution of propagating vibrational modes, in addition to non-propagating modes, revealing unexpectedly long mean free paths and ballistic thermal transport for heat carriers in amorphous silica. The fundamental vibrational modes in amorphous silica are further investigated using spectral-dependent Boltzmann transport equation simulations and molecular dynamics with machine learning potentials, showing good agreement with experimental results.
