The Effects of Post-Thermal Annealing on the Emission Spectra of GaAs/AlGaAs Quantum Dots grown by Droplet Epitaxy
Pilkyung Moon, J. D. Lee, S. K. Ha +5
We fabricated GaAs/AlGaAs quantum dots by droplet epitaxy method, and obtained the geometries of the dots from scanning transmission electron microscopy data. Post-thermal annealin…
Attosecond streaking of core lines of copper dihalides
J. D. Lee
In the attosecond (as) streaking of Cu 3s core-level photoemission of copper dihalides, we predict theoretically that the satellite () is emitted later than the main line ($3…
Control of carrier transport in GaAs by longitudinal-optical phonon-carrier scattering using a pair of laser pump pulses
Muneaki Hase, Daisuke Hayashi, J. D. Lee
We demonstrate optical control of the LO phonon-plasmon coupled (LOPC) modes in GaAs by using a femtosecond pump-pulse pair. The relaxation time of the plasmon-like LOPC mode signi…
Correlation, excitation, and relaxation of the antiferromagnetic nanoparticle
J. D. Lee
We study the dynamics of spins in the canted antiferromagnetic hematite nanoparticles -FeO. The system includes an antiferromagnetic exchange () between two sublattic…
Hidden glassy behaviors in an ideal Heisenberg Kagomé antiferromagnet
J. D. Lee
Dynamics of classical Heisenberg spins, , on the Kagomé lattice has been studied. An ideal Heisenberg Kagomé antiferromagnet is known to remain disord…
Photoemission and x-ray absorption spectroscopy study of electron-doped colossal magnetoresistance manganite: La0.7Ce0.3MnO3 film
S. W. Han, J. -S. Kang, K. H. Kim +11
The electronic structure of La0.7Ce0.3MnO3 (LCeMO) thin film has been investigated using photoemission spectroscopy (PES) and x-ray absorption spectroscopy (XAS). The Ce 3d core-le…
