Topological insulator single-electron transistors for charge sensing applications
Omargeldi Atanov, Junya Feng, Jens Brede +2
We present topological insulator (TI)-based single-electron transistors (SETs) as magnetic-field-compatible charge sensing devices that are easily integrable with TI-superconductor…
Point-contact Andreev reflection spectroscopy of layered superconductors with device-integrated diamond anvil cells
Che-hsuan Ku, Omargeldi Atanov, King Yau Yip +9
Superconductors that can be mechanically exfoliated are an interesting platform for exploring superconducting properties tuned by layer thickness. These layered superconductors are…
Thermodynamic signatures of a potential Fulde-Ferrell-Larkin Ovchinnikov state in the isotropic superconductor Ti4Ir2O
Jiaqi Hu, Yat Hei Ng, Omargeldi Atanov +3
This study presents an investigation of the isotropic superconductor Ti4Ir2O, focusing on its magnetic field vs. temperature phase diagram near and above the Pauli limit for superc…
Proximity-induced quasi-one-dimensional superconducting quantum anomalous Hall state: a promising scalable top-down approach towards localized Majorana modes
Omargeldi Atanov, Wai Ting Tai, Ying-Ming Xie +14
In this work, ~100 nm wide quantum anomalous Hall insulator (QAHI) nanoribbons are etched from a two-dimensional QAHI film. One part of the nanoribbon is covered with superconducti…
Discovery of Superconductivity in NbSiSb with a VSiSb-Type Structure and Implications of Interstitial Doping on its Physical Properties
Manuele D. Balestra, Omargeldi Atanov, Robin Lefèvre +4
We report on the discovery, structural analysis, and the physical properties of NbSiSb -- a hitherto unknown compound crystallizing in the VSiSb-type structure with…
Interfacial superconductivity and zero bias peak in quasi-one-dimensional Bi2Te3/Fe1+yTe heterostructure nanostructures
Man Kit Cheng, Cheuk Yin Ng, Sui Lun Ho +5
Bi2Te3/Fe1+yTe heterostructures are known to exhibit interfacial superconductivity between two non-superconducting materials: Fe1+yTe as the parent compound of Fe-based superconduc…
-vestigial nematic order due to superconducting fluctuations in the doped topological insulator NbBiSe and CuBiSe
Chang-woo Cho, Junying Shen, Jian Lyu +10
A state of matter with a multi-component order parameter can give rise to vestigial order. In the vestigial phase, the primary order is only partially melted, leaving a remaining s…
Spectroscopic Fingerprint of Chiral Majorana Modes at the Edge of a Quantum Anomalous Hall Insulator / Superconductor Heterostructure
J. Shen, J. Lyu, J. Z. Gao +14
With the recent discovery of the quantum anomalous Hall insulator (QAHI), which exhibits the conductive quantum Hall edge states without external magnetic field, it becomes possibl…
