Kapitza-resistance-like exciton dynamics in atomically flat MoSe-WSe lateral heterojunction
Hassan Lamsaadi, Dorian Beret, Ioannis Paradisanos +13
Being able to control the neutral excitonic flux is a mandatory step for the development of future room-temperature two-dimensional excitonic devices. Semiconducting Monolayer Tran…
Unidimensional model of the ad-atom diffusion on a substrate submitted to a standing acoustic wave II. Solutions of the ad-atom motion equation
Nicolas Combe, C. Taillan, J. Morillo
The ad-atom dynamic equation, a Langevin type equation is analyzed and solved using some non-linear analytical and numerical tools. We noticeably show that the effect of the surfac…
Unidimensional model of the ad-atom diffusion on a substrate submitted to a standing acoustic wave I. Derivation of the ad-atom motion equation
Nicolas Combe, C. Taillan, J. Morillo
The effect of a standing acoustic wave on the diffusion of an ad-atom on a crystalline surface is theoretically studied. We used an unidimensional space model to study the ad-atom+…
Number of observable features in the acoustic-Raman spectra of nanocrystals
Lucien Saviot, Nicolas Combe, Adnen Mlayah
Low-frequency Raman scattering spectra are presented for gold nanocrystals with diameters 3.5 and 13 nm. The frequencies of the Raman peaks but also their number are shown to vary…
The inverted pendulum, interface phonons and optic Tamm states
Nicolas Combe
The propagation of waves in periodic media is related to the parametric oscillators. We transpose the possibility that a parametric pendulum oscillates in the vicinity of its unsta…
Acoustic modes in metallic nanoparticles: atomistic versus elasticity modeling
Nicolas Combe, Lucien Saviot
The validity of the linear elasticity theory is examined at the nanometer scale by investigating the vibrational properties of silver and gold nanoparticles whose diameters range f…
