Stable and low loss oxide layer on α-Ta (110) film for superconducting qubits
Zengqian Ding, Boyi zhou, Tao Wang +5
The presence of amorphous oxide layers can significantly affect the coherent time of superconducting qubits due to their high dielectric loss. Typically, the surface oxides of supe…
High-quality superconducting α-Ta film sputtered on heated silicon substrate
Yanfu Wu, Zengqian Ding, Kanglin Xiong +1
Intrigued by the discovery of the long lifetime in the α-Ta/Al2O3-based Transmon qubit, researchers recently found α-Ta film is a promising platform for fabricating multi-qubits wi…
Fabrication of Al/AlOx/Al junctions with high uniformity and stability on sapphire substrates
Yuzhen Zheng, Shuming Li, Zengqian Ding +3
Tantalum and aluminum on sapphire are widely used platforms for qubits of long coherent time. As quantum chips scale up, the number of Josephson junctions on Sapphire increases. Th…
Coherent epitaxy of trilayer nickelate (Nd0.8Sr0.2)4Ni3O10 films by high-pressure magnetron sputtering
Jiachang Bi, Yujuan Pei, Ruyi Zhang +6
Rare-earth (R) nickelates (such as perovskite RNiO3, trilayer R4Ni3O10, and infinite layer RNiO2) have attracted tremendous interest very recently. However, unlike widely studied R…
Ultrafast triggering of insulator-metal transition in two-dimensional VSe
Deepnarayan Biswas, Alfred J. H. Jones, Paulina Majchrzak +24
Assembling transition metal dichalcogenides (TMDCs) at the two-dimensional (2D) limit is a promising approach for tailoring emerging states of matter such as superconductivity or c…
Interfacial Coupling and Electronic Structure of Two-Dimensional Silicon Grown on the Ag(111) Surface at High Temperature
Jiagui Feng, Sean Wagner, Pengpeng Zhang
Freestanding silicene, a monolayer of Si arranged in a honeycomb structure, has been predicted to give rise to massless Dirac fermions, akin to graphene. However, Si structures gro…
Evolution of the Surface Structures on SrTiO(110) Tuned by Ti or Sr Concentration
Zhiming Wang, Fang Yang, Zhiqiang Zhang +5
The surface structure of the SrTiO(110) polar surface is studied by scanning tunneling microscopy and X-ray photoelectron spectroscopy. Monophased reconstructions in (5…
