We address two finite-size effects in perpendicular transport through multilayers of ferromagnetic and normal metal layers: i the transport properties depend on the magnetic layer thickness when of the order or thinner than the spin-flip diffusion length and ii magnetic layers with thickness approaching the magnetic coherence length become transparent for spin currents polarized perpendicular t...
Diffusion MRI provides a non-invasive means to characterize tissue microstructure at varying length scales. Apparent diffusion coefficients (ADCs) of tissue water may be measured at relatively long diffusion times with conventional pulsed gradient spin echo (PGSE) methods, or at much shorter effective diffusion times using oscillating gradient spin echo (OGSE) methods. The manner in which ADC d...
introduction the movement and fate of solutes in the subsurface in affected by a large number of physical, chemical processes requiring a broad array of mathematical and physical sciences to study and describe solute transport. the dispersion is an important parameter in the advection – dispersion equation, which is used in assessing, and solving the problems related to the contamination and th...
Local recombination properties of threading screw and edge dislocations in 4H–SiC epitaxial layers have been studied using electron beam induced current !EBIC". The minority carrier diffusion length in the vicinity of dislocations was found to vary with dislocation type. Screw dislocations had a more pronounced impact on diffusion length than the edge dislocations, evidencing stronger recombina...
