Lattice Vibration Study Of Silica Nanoparticle In Suspension
… molecules near the particle surface and the lattice vibration of the nanoparticle. The phonon transfer through the second layer allows the nanofluid thermal conductivity to increase by 23%-27% compared to the base fluid water for 2% concentration of nanosilica.

First-principles Studies of Lattice Vibration and Electron Topology
… phonons, the elementary energy that constitutes vibration. More importantly, the integration of quantum theory into high-performance computing technology has given rise to the first-principles study, i.e. harnessing numerical algorithms and supercomputing power to solve the quantum equations …

Two quantum photoconductivity in potassium iodide
… in mobility as the longitudinal optical modes of lattice vibration freeze out. The electric and magnetic field dependences indicate higher mobilities than usually found in colored alkali halide crystals.

Dynamics of Energy Carriers in Solids During Interaction with Ultrafast Laser Pulses
… are mainly attributed to bandfilling and lattice heating, which can reflect the relaxation of photoexcited carriers. ^ In addition to the dynamics of electrons and holes, lattice vibration can also be manifested in the time domain by ultrafast spectroscopy. Our study shows that the guest …

AN EXPLORATION OF DEFECT-BASED SINGLE PHOTON SOURCES: ZINC OXIDE AND HEXAGONAL BORON NITRIDE
… 682 nm. These results are well described by a lattice vibration model that considers piezoelectric coupling to in-plane acoustic phonons. Lastly, we investigate the polarization selection rules and compare our findings with the predictions of the Huang-Rhys model. Our survey reveals that a …
