The Discrete Noise of Magnons
S. Rumyantsev, M. Balinskiy, F. Kargar +2
Magnonics is a rapidly developing subfield of spintronics, which deals with devices and circuits that utilize spin currents carried by magnons - quanta of spin waves. Magnon curren…
Strong Hot Carrier Effects Observed in a Single Nanowire Heterostructure
Iraj Abbasian Shojaei, Samuel Linser, Giriraj Jnawali +9
We use Transient Rayleigh Scattering to study the thermalization of hot photoexcited carriers in single GaAsSb/InP nanowire heterostructures. By comparing the energy loss rate in s…
Graphene Composites with Dual Functionality: Electromagnetic Shielding and Thermal Management
Fariborz Kargar, Zahra Barani, Michael G. Balinskiy +3
We report on the synthesis and characterization of the epoxy-based composites with the few-layer graphene fillers, which are capable of the duel functional applications. It was fou…
Thermal Percolation Threshold and Thermal Properties of Composites with Graphene and Boron Nitride Fillers
Fariborz Kargar, Zahra Barani, Jacob S. Lewis +5
We investigated thermal properties of the epoxy-based composites with a high loading fraction - up to f=45 vol.% - of the randomly oriented electrically conductive graphene fillers…
Acoustic Phonon Dispersion Engineering in Bulk Crystals via Incorporation of Dopant Atoms
Fariborz Kargar, Elias H. Penilla, Ece Aytan +3
We report results of Brillouin - Mandelstam spectroscopy of transparent alumina crystals with Nd dopants. The ionic radius and atomic mass of Nd atoms are distinctively different f…
