Phonon Transport Controlled by Ferromagnetic Resonance

Ferromagnetic resonance

Ferromagnetic Resonance

Ferromagnetism is used to characterize magnetic behavior of a material, such as the strong attraction to a permanent magnet. The origin of this strong magnetism is the presence of a spontaneous magnetization which is produced by a parallel alignment of spins. Instead of a parallel alignment of all the spins, there can be an anti-parallel alignment of unequal spins. This results in a spontaneous...

Phonon-Assisted Electronic Transport through Double Quantum Dot System Coupled to Ferromagnetic Leads

Phonon-assisted electronic tunneling is studied through a double quantum dot coupled in parallel to ferromagnetic electrodes. The current voltage characteristics for the system are derived within the nonequilibrium Green function technique based on equation of motion. It is found that additional phonon-induced resonance peaks appear in the spectral function on both sides of the main resonances ...

Phonon Transport in Graphene

Properties of phonons – quanta of the crystal lattice vibrations – in graphene have attracted strong attention of the physics and engineering communities. Acoustic phonons are the main heat carriers in graphene near room temperature while optical phonons are used for counting the number of atomic planes in Raman experiments with few-layer graphene. It was shown both theoretically and experiment...

Phonon Transport in Nanostructures

Recent experiments aiming to produce TiO2 nanostructures have been riddled with complications. It has been found that an undesired reaction occurs with the water used in the flaking process producing a sulphurous smell. This product suggests the production of TiOxS2−x in the layered crystal structure. This nanostructure has great potential benefits for the construction of semiconductor devices ...
