Development of a Scalable Quantum Memory Platform -- Materials Science of Erbium-Doped TiO Thin Films on Silicon
Manish Kumar Singh, Gary Wolfowicz, Jianguo Wen +6
Rare-earth ions (REI) have emerged as an attractive candidate for solid-state qubits, particularly as a quantum memory. Their 4f-4f transitions are shielded by filled 5s and 5p orb…
Two-dimensional superconductivity at the surfaces of KTaO3 gated with ionic liquid
Tianshuang Ren, Miaocong Li, Xikang Sun +8
The recent observation of superconductivity at the interfaces between KTaO3 and EuO (or LaAlO3) offers a new example of emergent phenomena at oxide interfaces. This superconductivi…
Atomistic Evidence of Nucleation Mechanism for the Direct Graphite-to-Diamond Transformation
Duan Luo, Liuxiang Yang, Hongxian Xie +7
The direct graphite-to-diamond transformation mechanism has been a subject of intense study and remains debated concerning the initial stages of the conversion, the intermediate ph…
Lonsdaleite: The diamond with optimized bond lengths and enhanced hardness
Liuxiang Yang, Kah Chun Lau, Zhidan Zeng +12
Diamond is known as the hardest substance due to its ultra-strong tetrahedral sp3 carbon bonding framework. The only weak link is its cubic cleavage planes between (111) buckled ho…
Discovery of two-dimensional anisotropic superconductivity at KTaO (111) interfaces
Changjiang Liu, Xi Yan, Dafei Jin +15
The unique electronic structure found at interfaces between materials can allow unconventional quantum states to emerge. Here we observe superconductivity in electron gases formed…
Machine Learning the Metastable Phase Diagram of Materials
Srilok Srinivasan, Rohit Batra, Duan Luo +8
Phase diagrams are an invaluable tool for material synthesis and provide information on the phases of the material at any given thermodynamic condition. Conventional phase diagram…
Ultrafast formation of transient 2D diamond-like structure in twisted bilayer graphene
Duan Luo, Dandan Hui, Bin Wen +17
Due to the absence of matching carbon atoms at honeycomb centers with carbon atoms in adjacent graphene sheets, theorists predicted that a sliding process is needed to form AA, AB,…
Atomistic manipulation of reversible oxidation and reduction in Ag by electron beam
Huaping Sheng, He Zheng, Lifen Wang +6
Employing electrons for direct control of nanoscale reaction is highly desirable since it provides fabrication of nanostructures with different properties at atomic resolution and…
Stabilization of highly polar BiFeO-like structure: a new interface design route for enhanced ferroelectricity in artificial perovskite superlattices
Hongwei Wang, Jianguo Wen, Dean J. Miller +5
In ABO3 perovskites, oxygen octahedron rotations are common structural distortions that can promote large ferroelectricity in BiFeO3 with an R3c structure [1], but suppress ferroel…
Amplitude Contrast Imaging in High-Resolution Transmission Electron Microscopy of Ferroelectric Superlattice Film
Jianguo Wen, Dean J. Miller, Nestor J. Zaluzec +3
To date, high-resolution electron microscopy has largely relied on using the phase of the exit wave function at the exit surface to form a high-resolution electron microscopic imag…
Doubling the Critical Current Density of High Temperature Superconducting Coated Conductors through Proton Irradiation
Y. Jia, M. LeRoux, D. J. Miller +11
The in-field critical current of commercial YBa2Cu3O7 coated conductors can be substantially enhanced by post-fabrication irradiation with 4 MeV protons. Irradiation to a fluence o…
