摘要

二维(2D)磁铁材料具有优良的电学和机械性能，并可用于创建二维纳米机电系统。然而，大多数二维磁体的居里温度很低，限制了其实际应用。本文基于分子束外延生长了晶圆级高品质的碲化铁锗(Fe_5+xGeTe₂)薄膜，并构建了范德华铁磁低通滤波器。通过原位铁掺杂，Fe_5+xGeTe₂体系的居里温度可以从260 ~ 380 K连续调制。与不带磁芯的电感相比，采用少层Fe_5+xGeTe₂制备平面螺旋电感在室温下的电感增强了74%。基于高性能电感器，课题组进一步构建了一系列巴特沃斯低通滤波器，首次实现了截止频率可调的、动态范围高达40dB的低通滤波器。通过在电感-电容电路中使用不同的电感器，可以将-3 dB截止频率从18 Hz调谐到30 Hz。

摘要

二维过渡金属二硫族化合物是下一代电子和自旋电子学的潜在平台。层状Weyl半金属(W,Mo)Te₂系列具有结构相变、不饱和磁阻、超导性和奇特的拓扑物理特性。然而，在不施加高压情况下，块体(W,Mo)Te₂的超导临界温度仍然很低。本文发现，当Ta掺杂到达0≤x≤0.22时，Mo_1−xTa_xTe₂单晶的超导性显著增强，转变温度提升到7.5 K，可以归因于费米能级态密度的增加。此外，在Mo_1−xTa_xTe₂ (x = 0.08) T_d相中观察到超过泡利极限的垂直上临界场增加到14.5 T，这可能源于空间反演对称性破环，导致非常规的单重态-三重态混合超导。这项工作为探索过渡金属二硫族化合物的奇异超导性和拓扑物理提供了新的途径。

PPMS Resistivity + MPMS

The electrical transport measurements were carried out using a physical property measurement system (PPMS) (Dynacool-14T, Quantum Design). A superconducting quantum interference device magnetometer (SQUID) (MPMS, Quantum Design) was used to measure the magnetization of bulk crystals.

Room-Temperature Magnetism in 2D MnGa₄-H Induced by Hydrogen Insertion. Adv Mater (2023)

摘要

二维室温磁性材料在未来的自旋电子器件中具有重要意义，但目前的报道很少。本文采用等离子体增强化学气相沉积方法制备了厚度为2.2 nm的二维室温磁性MnGa₄-H单晶。H₂等离子体的使用使得氢原子可以很容易地插入到MnGa₄晶格中来调节原子距离和电荷态，从而在不破坏结构构型的情况下实现铁磁性。所获得的二维MnGa₄-H晶体具有高质量、空气稳定性和热稳定性，居里温度更是高达620K以上。这项工作丰富了二维室温铁磁材料家族，为基于二维磁性合金的自旋电子器件开发提供了新的可能。

PPMS Resistivity + MPMS

The magnetic susceptibility and magnetization measurements were carried out using a superconducting quantum interference device magnetometer (Quantum Design, MPMS-VSM). The longitudinal resistance was collected by a pulse relaxation method on a physical property measurement system (Quantum Design, PPMS-9T) varying from 300 to 2 K under zero magnetic fields. The Hall electrical resistance was measured by a physical property measurement system calorimeter (Quantum Design, PPMS-9T).

Unveiling strong ion-electron-lattice coupling and electronic antidoping in hydrogenated perovskite nickelate. Adv Mater (2023)

摘要

原子尺度解码关联材料中的离子-电子-晶格耦合和能带结构具有重要应用前景，但也极具挑战，因为这些自由度之间具有强烈而复杂的相关性。本文以钙钛矿镍酸盐NdNiO₃外延薄膜为模型体系，证明了氢离子诱导的巨大晶格畸变和NiO₆八面体旋转增强，从而在一系列衬底上形成了晶格膨胀大于10%的新型氢化HNdNiO₃相。此外，在离子-电子协同掺杂的作用下，发现了电子反掺杂，即掺杂电子主要填充基态氧的2p空穴，而不是将Ni的氧化态从Ni³⁺转变为Ni²⁺，主导了金属-绝缘体的转变。最后，通过电场控制的氢离子嵌入及其与晶格和电子电荷的强耦合，制备出具有不同结构态和电子态的选择性微米尺度图案。研究结果为关联物理中离子-电子-晶格强耦合提供了直接证据，并展示了其在设计新型材料和器件方面的潜在应用。

摘要

范德华磁体的发现为电控磁性提供了一个新的平台。近来实验表明，范德华磁体的磁性可以通过栅极调制，但大部分都具有易失性，并且要求栅极电压不低于几伏。本文实现了Fe₃GeTe₂/MgO异质结构中交换偏置和矫顽力场的非易失性调控，栅极电压低至几十mV，比以往实验降低了两个数量级。通过MgO溅射，在Fe₃GeTe₂中形成离子辐照相，进而在此异质结构中获得了交换偏置效应，在5~20 mV的电压范围内调制偏置700~0Oe。氧化Fe₃GeTe₂具有高稳定性，来自辐照相的氧在电压驱动下与Fe₃GeTe₂结合，引起非易失磁调制，在切断栅压后仍可以保留。本文的发现展示了一种调节范德华磁体磁性的方法，为使用范德华材料制造全固体、非易失和低耗散的纳米电子器件开辟了新道路。

摘要

层状材料中范德华隙的存在创造了大量不同于传统材料的有趣现象。例如，加压可以沿堆叠方向产生各向异性晶格收缩和/或层间滑动，并诱发一系列压力依赖的奇特物性。本文报告了β''-In₂Se₃中巨大压阻性。仅压缩1.2 GPa，β''-In₂Se₃薄片的电阻率下降了6个数量级，产生了一个巨大的压阻系数π_p=−5.33 GPa⁻¹。同时，样品从半导体转变为半金属，并未伴随结构相变。令人惊讶的是，线性二色性研究和理论第一原理模型表明，这些现象并非范德华隙收缩或滑动导致的，而是由五层结构内部相关原子运动主导的，主要是中间层Se原子向其高对称位置移动。原子运动与能带结构调制和面内铁电偶极子密切有关。本文不仅发现了一种优秀的压阻材料，而且指出了超越范德华间隙的层内原子运动的重要性。

摘要

二维(2D)材料因具有大线性磁阻(LMR)而在磁存储或传感器器件领域极具潜力。本文通过化学气相沉积法(CVD) 制备二维MoO₂纳米片，观察到其具有大LMR行为和非线性霍尔行为。得到的MoO₂纳米片具有菱形形状和高结晶度。电学研究表明，MoO₂纳米片具有优异的金属性，在2.5 K下的电导率高达3.7×10⁷ S m^–1。磁阻方面，MoO₂纳米片的大LMR在3 K和-9T时高达455%，厚度依赖实验表明，LMR值随着纳米片厚度的增加而增加。此外，磁场依赖霍尔电阻呈非线性，随温度升高而减小。本文的研究强调，MoO₂纳米片是一种有前景的基础研究材料，在磁存储器件中具有潜在的应用前景。

摘要

窄带半导体中高性能热电(TE)材料的研究存在瓶颈，本文另辟蹊径，发现金属化合物TiFe_xCu_2x−1Sb和TiFe_1.33Sb热电性质可与最先进的TE材料相媲美，其热功率和热电优值zTs超过众多TE半导体的。2-700 K的准线性温度依赖电阻率和低温下对数温度依赖的电子比热与高热功率共存，表明了电子的非费米液体(NFL)量子临界行为与TE输运的强耦合。电子结构分析揭示了反铁磁(AFM)有序和类近藤自旋补偿之间的竞争，以及平行双通道近藤效应。T依赖磁化率曲线符合强局部关联的量子临界假设。本文证明了高TE性能、NFL量子临界性和磁涨落之间的相关性，为未来的研究开辟了方向。
