Three-dimensional atomic positions and local chemical order of medium- and high-entropy alloys
Saman Moniri, Yao Yang, Yakun Yuan +9
Medium- and high-entropy alloys (M/HEAs) mix multiple principal elements with near-equiatomic composition and represent a paradigm-shift strategy for designing new materials for me…
Thermodynamic and electron-transport properties of Ca3Ru2O7 from first-principles phonon calculations and Boltzmann transport theory
Yi Wang, Yihuang Xiong, Tiannan Yang +6
This work demonstrates a first-principles-based approach to obtaining finite temperature thermal and electronic transport properties which can be employed to model and understand m…
Atomic-scale identification of the active sites of nanocatalysts
Yao Yang, Jihan Zhou, Zipeng Zhao +15
Alloy nanocatalysts have found broad applications ranging from fuel cells to catalytic converters and hydrogenation reactions. Despite extensive studies, identifying the active sit…
Capturing 3D atomic defects and phonon localization at the 2D heterostructure interface
Xuezeng Tian, Xingxu Yan, Georgios Varnavides +9
The 3D local atomic structures and crystal defects at the interfaces of heterostructures control their electronic, magnetic, optical, catalytic and topological quantum properties,…
Subterahertz collective dynamics of polar vortices
Qian Li, Vladimir A. Stoica, Marek Paściak +29
The collective dynamics of topological structures have been of great interest from both fundamental and applied perspectives. For example, the studies of dynamical properties of ma…
Direct observation of 3D atomic packing in monatomic amorphous materials
Yakun Yuan, Dennis S. Kim, Jihan Zhou +10
Liquids and solids are two fundamental states of matter. However, due to the lack of direct experimental determination, our understanding of the 3D atomic structure of liquids and…
RESIRE: real space iterative reconstruction engine for Tomography
Minh Pham, Yakun Yuan, Arjun Rana +2
Tomography has made a revolutionary impact on diverse fields, ranging from macro-/mesoscopic scale studies in biology, radiology, plasma physics to the characterization of 3D atomi…
Determining the three-dimensional atomic structure of a metallic glass
Yao Yang, Jihan Zhou, Fan Zhu +12
Amorphous solids such as glass are ubiquitous in our daily life and have found broad applications ranging from window glass and solar cells to telecommunications and transformer co…
Ultrafast quasiparticle dynamics in correlated semimetal CaRuO
Yakun Yuan, Peter Kissin, Danilo Puggioni +7
The correlated polar semimetal CaRuO exhibits a rich phase diagram including two magnetic transitions (=56 K and =48 K) with the appearance of an insulating-l…
Correlating 3D atomic defects and electronic properties of 2D materials with picometer precision
Xuezeng Tian, Dennis S. Kim, Shize Yang +10
The exceptional electronic, optical and chemical properties of two-dimensional materials strongly depend on the 3D atomic structure and crystal defects. Using Re-doped MoS2 as a mo…
Linear and nonlinear optical probe of the ferroelectric-like phase transition in a polar metal, LiOsO3
Haricharan Padmanabhan, Yoonsang Park, Danilo Puggioni +7
LiOsO3 is one of the first materials identified in a recent literature as a 'polar metal', a class of materials that are simultaneously noncentrosymmetric and metallic. In this wor…
Artificial two-dimensional polar metal at room temperature
Yanwei Cao, Zhen Wang, Se Young Park +16
Polar metals, commonly defined by the coexistence of polar crystal structure and metallicity, are thought to be scarce because the long-range electrostatic fields favoring the pola…
Does the Dirac Cone Exist in Silicene on Metal Substrates?
Ruge Quhe, Yakun Yuan, Jiaxin Zheng +6
Absence of the Dirac cone due to a strong band hybridization is revealed to be a common feature for epitaxial silicene on metal substrates according to our first-principles calcula…
Tunable band gap in germanene by surface adsorption
Meng Ye, Ruge Quhe, Jiaxin Zheng +7
Opening a sizable band gap in the zero-gap germanene without heavy loss of carrier mobility is a key issue for its application in nanoelectronic devices such as high-performance fi…
