Measurements of Transverse Relaxation of Electron Spins in Semiconductors

The main activities of this program were to measure the homogeneous spin-phase memory time T2 of electron spins on donor sites at low temperatures in Si:P and to execute a major upgrade of the ESR spectrometer to enable more comprehensive measurements. Most of the measurements were made using the pulsed ESR spectrometer in Prof. Holczer’s laboratory; these were complimented by measurements carr...

Importance of spin-orbit interaction for the electron spin relaxation in organic semiconductors.

Despite the great interest organic spintronics has recently attracted, there is only a partial understanding of the fundamental physics behind electron spin relaxation in organic semiconductors. Mechanisms based on hyperfine interaction have been demonstrated, but the role of the spin-orbit interaction remains elusive. Here, we report muon spin spectroscopy and time-resolved photoluminescence m...

Electron vortices in semiconductors devices

The hydrodynamic model of electron transport in semiconductors is analyzed and, in analogy with vortices in fluid mechanics, the curl of electron velocity is defined as electron vorticity, and the transport equation for the electron vorticity is derived. Aside from the classical hydrodynamic sources of vorticity, collision terms in the continuity and momentum equations are identified as sources...

Electron Distribution in Degenerate Semiconductors

As we’ve discussed, to get the right density of states we should replace m by me . In addition, the energy that appears in the square root in the density of states really came from changing variables from momentum to energy. At the bottom of the conduction band, the electrons presumably have very little momentum. That is, the first state to be filled corresponds to an electron wave which is a s...

Light-induced nuclear quadrupolar relaxation in semiconductors

Light excitation of a semiconductor, known to dynamically-polarize the nuclear spins by hyperfine contact interaction with the photoelectrons, also generates an intrinsic nuclear depolarization mechanism. This novel relaxation process arises from the modulation of the nuclear quadrupolar Hamiltonian by photoelectron trapping and recombination at nearby localized states. For nuclei near shallow ...
