Enhancement of Spin Coherence using Q-factor Engineering in Semiconductor Microdisk Lasers
S. Ghosh, W. H. Wang, F. M. Mendoza +5
Semiconductor microcavities offer unique means of controlling light-matter interactions, which have led to the development of a wide range of applications in optical communications…
Spin dynamics in electrochemically charged CdSe quantum dots
N. P. Stern, M. Poggio, M. H. Bartl +3
We use time-resolved Faraday rotation to measure coherent spin dynamics in colloidal CdSe quantum dots charged in an electrochemical cell at room temperature. Filling of the 1Se el…
Electrical initialization and manipulation of electron spins in an L-shaped strained n-InGaAs channel
Y. K. Kato, R. C. Myers, A. C. Gossard +1
An L-shaped strained n-InGaAs channel is used to polarize and subsequently rotate electron spins solely by means of electric fields. Precession of electrically-excited spins in the…
Room temperature spin coherence in ZnO
S. Ghosh, V. Sih, W. H. Lau +5
Time-resolved optical techniques are used to explore electron spin dynamics in bulk and epilayer samples of n-type ZnO as a function of temperature and magnetic field. The bulk sam…
High-field optically detected nuclear magnetic resonance in GaAs
M. Poggio, D. D. Awschalom
A method for high-field optically detected nuclear magnetic resonance (ODNMR) is developed sensitive to 10**8 nuclei. Nuclear spin transitions are induced using a radio frequency c…
Electron spin interferometry using a semiconductor ring structure
Y. K. Kato, R. C. Myers, A. C. Gossard +1
A ring structure fabricated from GaAs is used to achieve interference of the net spin polarization of conduction band electrons. Optically polarized spins are split into two packet…
