Sub-unit cell engineering of CrVO superlattice thin films
Claudio Bellani, Simon Mellaerts, Wei-Fan Hsu +13
Ordered corundum oxides introduce new prospects in the field of functional oxides thin films, complementing the more widely studied class of ABO perovskites. In this work, we t…
Effect of C additives with 0.5% in weight on structural, optical and superconducting properties of Ta-Nb-Hf-Zr-Ti high entropy alloy films
Tien Le, Yeonkyu Lee, Dzung T. Tran +10
We investigated the superconducting (SC) properties of Ta-Nb-Hf-Zr-Ti high-entropy alloy (HEA) thin films with 0.5% weight C additives. The C additives stabilize the structural pro…
Roles of Fe-ion irradiation on MgB thin films: Structural, superconducting, and optical properties
Dzung T. Tran, Tien Le, Yu-Seong Seo +8
The effects of Fe-ion irradiation on the crystal structure and superconducting properties of MgB thin films were investigated. Pristine samples were prepared using hybrid physi…
Hybridization gap and -electron effect evolutions with Cd- and Sn-doping in CeCoIn via infrared spectroscopy
Myounghoon Lee, Yu-Seong Seo, Seulki Roh +4
We investigated hole (Cd)- and electron (Sn)-doped CeCoIn (CeCo(In) ( = Cd or Sn)) using infrared spectroscopy. Doping-dependent hybridization gap distributio…
Direct Observation of d-Wave Superconducting Gap Symmetry in Pressurized La3Ni2O7-delta Single Crystals
Zi-Yu Cao, Di Peng, Seokmin Choi +21
The recent discovery of superconductivity in pressure-stabilized bulk La3Ni2O7-delta, with a critical temperature (Tc) exceeding 77 K, has opened a new frontier in high-temperature…
Evidence of surface -wave superconductivity and higher-order topology in MoTe
Sangyun Lee, Myungjun Kang, Duk Y. Kim +4
Exploration of nontrivial superconductivity and electronic band topology is at the core of condensed matter physics and applications to quantum information. The transition-metal di…
