Interface-Enhanced Superconductivity in Ultrathin TiN Proximitized by Topological Insulators
Renjie Xie, Bowen Hao, Min Ge +11
High-quality topological insulator-superconductor (TI-SC) heterostructure with an atomically sharp and well-controlled interface is crucial for realizing topological superconductiv…
Crystal orientation-dependent oxidation of epitaxial TiN films with tunable plasmonics
Ruyi Zhang, Qian-Ying Ma, Haigang Liu +9
Titanium nitride (TiN) is a paradigm of refractory transition metal nitrides with great potential in vast applications. Generally, the plasmonic performance of TiN can be tuned by…
Metallic interfaces in a CaTiO/LaTiO heterostructure
Shaozhu Xiao, Fangdi Wen, Xiaoran Liu +8
Almost all oxide two-dimensional electron gases are formed in SrTiO-based heterostructures and the study of non-SrTiO systems is extremely rare. Here, we report the realiza…
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…
Anomalous orbital structure in two-dimensional titanium dichalcogenides
Banabir Pal, Yanwei Cao, Xiaoran Liu +6
Generally, lattice distortions play a key role in determining the ground states of materials. Although it is well known that trigonal distortions are generic to most two-dimensiona…
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…
