Resonant photoluminescence and excitation spectroscopy of CdSe/ZnSe and CdTe/ZnTe self-assembled quantum dots
T. A. Nguyen, S. Mackowski, H. Rho +8
We show that two major carrier excitation mechanisms are present in II-VI self-assembled quantum dots. The first one is related to direct excited state - ground state transition. I…
Resonant and non-resonant PL and PLE spectra of CdSe/ZnSe and CdTe/ZnTe self-assembled quantum dots
T. A. Nguyen, S. Mackowski, L. M. Robinson +6
Using micro- and nano-scale resonantly excited PL and PLE, we study the excitonic structure of CdSe/ZnSe and CdTe/ZnTe self assembled quantum dots (SAQD). Strong resonantly enhance…
Magneto-photoluminescence measurements of symmetric and asymmetric CdSe/ZnSe self-assembled quantum dots
K. P. Hewaparakrama, N. Mukolobwiez, L. M. Smith +4
We study the excitonic structure of CdSe/ZnSe self assembled quantum dots (SAQD) by magneto-photoluminescence (PL) spectroscopy. Using fixed 200 nm apertures through a metal film,…
Probing hole-induced ferromagnetic exchange in magnetic semiconductors by inelastic neutron scattering
H. Kepa, Le Van Khoi, C. M. Brown +4
The effect of hole doping on the exchange coupling of the nearest neighbor (NN) Mn pairs in ZnMnTe is probed by inelastic neutron scattering. The difference in the NN e…
Low temperature annealing studies of Ga1-xMnxAs
I. Kuryliszyn, T. Wojtowicz, X. Liu +7
High- and low-field magneto-transport measurements, as well as SQUID measurements of magnetization, were carried out on Ga1-xMnxAs epilayers grown by low temperature molecular beam…
Transport and magnetic properties of LT annealed Ga1-xMnxAs
I. Kuryliszyn, T. Wojtowicz, X. Liu +7
We present the results of low temperature (LT) annealing studies of Ga1-xMnxAs epilayers grown by low temperature molecular beam epitaxy in a wide range of Mn concentrations (0.01<…
