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…
Phonon hydrodynamics, thermal conductivity and second sound in 2D crystals
Pablo Scuracchio, Karl H. Michel, Francois M. Peeters
Starting from our previous work where we have obtained a system of coupled integro-differential equations for acoustic sound waves and phonon density fluctuations in 2D crystals, w…
Piezoelectricity in two-dimensional materials: a comparative study between lattice dynamics and ab-initio calculations
K. H. Michel, D. Cakır, C. Sevik +1
Elastic constant C_{11} and piezoelectric stress constant e_{1,11} of two-dimensional (2D) dielectric materials comprising h-BN, 2H MoS2 and other transition metal dichalcogenides…
Theory of anharmonic phonons in 2D crystals
K. H. Michel, S. Costamagna, F. M. Peeters
Anharmonic effects in an atomic monolayer thin crystal with honeycomb lattice structure are investigated by analytical and numerical lattice dynamical methods. Starting from a semi…
Boron Nitride Monolayer: A Strain-Tunable Nanosensor
M. Neek-Amal, J. Beheshtian, A. Sadeghi +2
The influence of triaxial in-plane strain on the electronic properties of a hexagonal boron-nitride sheet is investigated using density functional theory. Different from graphene,…
Theory of elastic anomalies at the gamma--alpha phase transition in solid Ce
K. H. Michel, A. V. Nikolaev
Starting from a model of 4f-electron generated quadrupolar densities on a compressible fcc lattice, the elastic anomalies at the Fm3m -> Pa3 phase transition are studied by means o…
