Size Effect of Local Current-Voltage Characteristics of MX Nanoflakes: Local Density of States Reconstruction from Scanning Tunneling Microscopy Experiments
Anna N. Morozovska, Hanna V. Shevliakova, Yaroslava Yu. Lopatina +7
Local current-voltage characteristics for low-dimensional transition metal dichalcogenides (LD-TMD), as well as the reconstruction of their local density of states (LDOS) from scan…
Flexoelectric and piezoelectric coupling in a bended MoS monolayer
Hanna V. Shevliakova, Semen O. Yesylevskyy, Ihor Kupchak +3
Low-dimensional (LD) transition metal dichalcogenides (TMDs) in the form of nanoflakes, which consist of one or several layers, are the subject of intensive fundamental and applied…
Flexo-Elastic Control Factors of Domain Morphology in Core-Shell Ferroelectric Nanoparticles: Soft and Rigid Shells
Eugene A. Eliseev, Anna N. Morozovska, Riccardo Hertel +4
Within the framework of the Landau-Ginzburg-Devonshire approach we explore the impact of elastic anisotropy, electrostriction, flexoelectric couplings, and mismatch strain on the d…
Correlation between corrugation-induced flexoelectric polarization and conductivity of low-dimensional transition metal dichalcogenides
Anna N. Morozovska, Eugene A. Eliseev, Hanna V. Shevliakova +5
Tunability of polar and semiconducting properties of low-dimensional transition metal dichalcogenides (TMDs) have propelled them to the forefront of fundamental and applied physica…
The influence of the distribution function of ferroelectric nanoparticles sizes on their electrocaloric and pyroelectric properties
Hanna V. Shevliakova, Anna N. Morozovska, Nicholas V. Morozosky +2
We consider a model of a nanocomposite based on non-interacting spherical single-domain ferroelectric nanoparticles of various sizes embedded in a dielectric matrix. The size distr…
Analytical description of the size effect on pyroelectric and electrocaloric properties of ferroelectric nanoparticles
Anna N. Morozovska, Eugene A. Eliseev, Maya D. Glinchuk +7
Using Landau-Ginzburg-Devonshire theory and effective medium approximation, we analytically calculate typical dependences of the pyroelectric and electrocaloric coefficients on ext…
