Magnetic Topological Semimetal Phase with Electronic Correlation Enhancement in SmSbTe
Krishna Pandey, Debashis Mondal, John William Villanova +14
The ZrSiS family of compounds hosts various exotic quantum phenomena due to the presence of both topological nonsymmorphic Dirac fermions and nodal-line fermions. In this material…
Thermoelectricity of Tin Selenide Monolayers Across a Structural Phase Transition
John W. Villanova, Salvador Barraza-Lopez
SnSe monolayers experience a temperature induced two-dimensional Pnm2 P4/nmm structural transformation precipitated by the softening of vibrational modes. The standard theo…
Colloquium: Physical properties of group-IV monochalcogenide monolayers
Salvador Barraza-Lopez, Benjamin M. Fregoso, John W. Villanova +2
We survey the state-of-the-art knowledge of ferroelectric and ferroelastic group-IV monochalcogenide monolayers. These semiconductors feature remarkable structural and mechanical p…
Topology of atomically thin soft ferroelectric membranes at finite temperature
John W. Villanova, Pradeep Kumar, Salvador Barraza-Lopez
One account of two-dimensional (2D) structural transformations in 2D ferroelectrics predicts an evolution from a structure with Pnm2 symmetry into a structure with square P4/nm…
Group-IV monochalcogenide monolayers: two-dimensional ferroelectrics with weak intra-layer bonds and a phosphorene-like monolayer dissociation energy
Shiva P. Poudel, John W. Villanova, Salvador Barraza-Lopez
We performed density functional theory calculations with self-consistent van der Waals corrected exchange-correlation (XC) functionals to capture the structure of black phosphorus…
Zeeman-splitting-induced Topological Nodal Structure and Anomalous Hall Conductivity in ZrTe
Yichul Choi, John W. Villanova, Kyungwha Park
We investigate the topological nodal structure of three-dimensional (3D) ZrTe driven by Zeeman splitting as a function of the direction of external magnetic (B) field by using…
