Slippery paraelectric transition metal dichalcogenide bilayers
Juan M. Marmolejo-Tejada, Joseph E. Roll, Shiva Prasad Poudel +2
Traditional ferroelectrics undergo thermally-induced phase transitions whereby their structural symmetry increases. The associated higher-symmetry structure is dubbed {\em paraelec…
Metastable piezoelectric group IV monochalcogenide monolayers with a buckled honeycomb structure
Shiva P. Poudel, Salvador Barraza-Lopez
Twelve two-dimensional group-IV monochalcogenide monolayers (SiS, SiSe, SiTe, GeS, GeSe, GeTe, SnS, SnSe, SnTe, PbS, PbSe, and PbTe) with a buckled honeycomb atomistic structure--b…
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…
Tuning the ferro- to para-electric transition temperature and dipole orientation of group-IV monochalcogenide monolayers
Salvador Barraza-Lopez, Thaneshwor P. Kaloni, Shiva P. Poudel +1
Coordination-related, two-dimensional (2D) structural phase transitions are a fascinating and novel facet of two-dimensional materials with structural degeneracies. Nevertheless, a…
