Spintronics: electron spin coherence, entanglement, and transport
S. Das Sarma, Jaroslav Fabian, Xuedong Hu +1
Prospect of building spintronic devices in which electron spins store and transport information has attracted strong attention in recent years. Here we present some of our represen…
Diffusons, Locons, Propagons: Character of Atomic Vibrations in Amorphous Si
Philip B. Allen, Joseph L. Feldman, Jaroslav Fabian +1
Numerical studies of amorphous silicon show that the lowest 4% of vibrational modes are plane-wave like ("propagons") and the highest 3% of modes are localized ("locons"). The rest…
Phonon-induced spin relaxation of conduction electrons in aluminum
Jaroslav Fabian, S. Das Sarma
Spin-flip Eliashberg function and temperature-dependent spin relaxation time are calculated for aluminum using realistic pseudopotentials. The spin-flip electron-…
Spin relaxation of conduction electrons
Jaroslav Fabian, S. Das Sarma
Prospect of building electronic devices in which electron spins store and transport information has revived interest in the spin relaxation of conduction electrons. Since spin-pola…
Theory of sound attenuation in glasses: The role of thermal vibrations
Jaroslav Fabian, Philip B. Allen
Sound attenuation and internal friction coefficients are calculated for a realistic model of amorphous silicon. It is found that, contrary to previous views, thermal vibrations can…
