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…
Beyond Graphene: Low-Symmetry and Anisotropic 2D Materials
Salvador Barraza-Lopez, Fengnian Xia, Wenjuan Zhu +1
Low-symmetry 2D materials---such as ReS and ReSe monolayers, black phosphorus monolayers, group-IV monochalcogenide monolayers, borophene, among others---have more complex…
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…
Tuning energy barriers by doping 2D group-IV monochalcogenides
Albert Du, Zachary Pendergrast, Salvador Barraza-Lopez
Structural degeneracies underpin the ferroic behavior of next-generation two-dimensional materials, and lead to peculiar two-dimensional structural transformations under external f…
Microscopic manipulation of ferroelectric domains in SnSe monolayers at room temperature
Kai Chang, Felix Küster, Brandon J. Miller +5
Two-dimensional (2D) van der Waals ferroelectrics provide an unprecedented architectural freedom for the creation of artificial multiferroics and non-volatile electronic devices ba…
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…
