Efficiently gate-tunable ferromagnetism in ferromagnetic semiconductor-Dirac semimetal p-n heterojunctions
Emma Steinebronn, Saurav Islam, Abhinava Chatterjee +15
We use molecular beam epitaxy to develop a gate tunable p-n heterojunction that interfaces a canonical Dirac semimetal, CdAs, and a ferromagnetic semiconductor, InM…
Hybridization of topologically distinct quartet modes in three-terminal graphene Josephson junctions
Asmaul Smitha Rashid, Le Yi, Takashi Taniguchi +4
Multiterminal Josephson junctions offer a powerful playground for exploring exotic superconducting and topological phenomena beyond the reach of conventional two-terminal devices.…
Successful growth of low carrier density -InSe single crystals using Se-flux in a modified Bridgman furnace
Soumi Mondal, Sreekant Anil, Saurav Islam +7
Indium selenide (InSe) has garnered significant attention for its intriguing properties and applications in batteries, solar cells, photodetectors and ferroelectric devices…
Examining the Spin Structure of Altermagnetic Candidate MnTe Grown with Near Ideal Stoichiometry
Qihua Zhang, Christopher J. Jensen, Alexander J. Grutter +11
Altermagnets are a recently-discovered class of materials with magnetic ordering that have a zero net magnetization and a momentum-dependent spin splitting in their band structure,…
Non-Hermitian Dynamics in Quantum Anomalous Hall Insulators
Le Yi, Emma Steinebronn, Asmaul Smitha Rashid +4
Magnetically doped topological insulators (TIs) exhibit two distinct phases: the quantum anomalous Hall (QAH) phase when the Fermi level resides within the surface gap, and a metal…
Quantum confinement effect in Sb thin films
Anuradha Wijesinghe, Yongxi Ou, Anjali Rathore +7
Antimony (Sb), an element with strong spin-orbit coupling, is predicted to undergo a topological phase transition from a topological semimetal to a topological insulator as its dim…
