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…
Structural, electrical, and magneto-optical characterization of paramagnetic GaMnAs quantum wells
M. Poggio, R. C. Myers, N. P. Stern +2
Growth of GaMnAs by molecular beam epitaxy is typically performed at low substrate temperatures (250C) and high As overpressures leading to the incorporation of excess As and Mn in…
Antiferromagnetic s-d exchange coupling in GaMnAs
R. C. Myers, M. Poggio, N. P. Stern +2
Measurements of coherent electron spin dynamics in Ga(1-x)Mn(x)As/Al(0.4)Ga(0.6)As quantum wells with 0.0006% < x < 0.03% show an antiferromagnetic (negative) exchange bewteen s-li…
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…
