Excitonic Landscape of Monolayer Transition-Metal Dichalcogenides: Experimental Discrepancies, Theoretical Advances, and Strain Dependence
Cem Sevik, Purushothaman Manivannan, Fulvio Paleari +1
Excitons in monolayer transition-metal dichalcogenides (TMDs) have garnered significant attention because of their large binding energies due to weakly screened Coulomb interaction…
Thermal Conductivity Limits of MoS and MoSe: Revisiting High-Order Anharmonic Lattice Dynamics with Machine Learning Potentials
Tugbey Kocabas, Murat Keceli, Tanju Gurel +2
Group-VI transition metal dichalcogenides (TMDs), MoS and MoSe, have emerged as prototypical low-dimensional systems with distinctive phononic and electronic properties, ma…
Strain-tuned magnetoelectric properties of monolayer NiX (X = I, Br): a first-principles analysis
Ali Ghojavand, Cem Sevik, Milorad V. Milošević
Using \textit{ab initio} methodology, we reveal a strain-mediated approach to precisely tune the magnetoelectric coupling and spin-driven emergent polarization of NiX (X = I, B…
Machine-Learning Interatomic Potential for Twisted Hexagonal Boron Nitride: Accurate Structural Relaxation and Emergent Polarization
Wilson Nieto Luna, Robin Smeyers, Cem Sevik +2
The emerging ferroelectric properties of two-dimensional (2D) heterostructures are at the forefront of science and prospective technology. In moiré bilayers, twisting or heterostru…
State- and momentum-dependent nonlinear Stark effect of interlayer excitons in bilayer WSe
Cem Sevik, Engin Torun, Milorad V. Milosevic +1
Interlayer excitons in van der Waals heterostructures offer rich collective phases, prospective optoelectronic applications, and versatile tunability, where control by electronic m…
Theory of a two-dimensional anharmonic piezoelectric crystal resonator
Karl H. Michel, Cem Sevik, Milorad V. Milosevic
We developed a lattice dynamical theory of an atomically-thin compressional piezoelectric resonator. Acoustic and optical dynamic displacement response functions are derived and ac…
