Atomically-precise Vacancy-assembled Quantum Antidots
Hanyan Fang, Harshitra Mahalingam, Xinzhe Li +16
Patterning antidots ("voids") into well-defined antidot lattices creates an intriguing class of artificial structures for the periodic modulation of 2D electron systems, leading to…
Prediction of three-fold fermions in a nearly-ideal Dirac semimetal BaAgAs
Sougata Mardanya, Bahadur Singh, Shin-Ming Huang +5
Materials with triply-degenerate nodal points in their low-energy electronic spectrum produce crystalline-symmetry-enforced three-fold fermions, which conceptually lie between the…
Spin-dependent scattering induced negative magnetoresistance in topological insulator Bi2Te3 nanowires
Biplab Bhattacharyya, Bahadur Singh, R. P. Aloysius +7
Studies of negative magnetoresistance in novel materials have recently been in the forefront of spintronic research. Here, we report an experimental observation of the temperature…
Saddle-point von Hove singularity and dual topological insulator state in PtHgSe
Barun Ghosh, Sougata Mardanya, Bahadur Singh +7
Saddle-point van Hove singularities in the topological surface states are interesting because they can provide a new pathway for accessing exotic correlated phenomena in topologica…
Topological Hourglass Dirac Semimetal in the Nonpolar Phase of AgBiO
Bahadur Singh, Barun Ghosh, Chenliang Su +3
Materials with tunable charge and lattice degrees of freedom provide excellent platforms for investigating multiple phases that can be controlled via external stimuli. We show how…
Tunable double-Weyl Fermion semimetal state in the SrSi materials class
Bahadur Singh, Guoqing Chang, Tay-Rong Chang +5
We discuss first-principles topological electronic structure of noncentrosymmetric SrSi materials class based on the hybrid exchange-correlation functional. Topological phase d…
Starfruit-like nodal semimetal to Dirac and Weyl semimetal state in CaAuAs
Bahadur Singh, Sougata Mardanya, Chenliang Su +3
Band-crossings occurring on a mirror plane are compelled to form a nodal loop in the momentum space without spin-orbit coupling (SOC). In the presence of other equivalent mirror pl…
Tunable room-temperature ferromagnet using an iron-oxide and graphene oxide nanocomposite
Aigu L. Lin, J. N. B. Rodrigues, Chenliang Su +7
Magnetic materials have found wide application ranging from electronics and memories to medicine. Essential to these advances is the control of the magnetic order. To date, most ro…
Seeding ice growth at ambient conditions using nano graphene oxide
Yi Zheng, C. L. Su, Jiong Lu +1
Water wetting on a hydrophobic surface at ambient conditions is disallowed by the nonpolar nature of the surface and high vapor pressure of water. However, the presence of sub-mill…
