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…
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…
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…
