CdSe nanocrystal quantum-dot memory

Applied Physics Letters, 2005
Memory effects in the electronic transport in CdSe nanocrystal (NC) quantum-dot arrays have been observed and characterized. Conduction through a NC array can be reduced with a negative voltage and then restored with a positive voltage. Light can also be used to restore or even increase the NC array conduction.

Gain processes in CdSe quantum dots

Journal of Crystal Growth, 1996
The bleaching of the absorption has been studied for CdSe quantum dots in the strong confinement limit by nanosecond pump-and-probe spectroscopy. For high excitation we detect optical gain in a broad spectral region below the absorption edge accompanied by a new peak in the luminescence.

Gain Dynamics in CdSe Quantum Dots

1996
Quantum dots in the strong confinement regime, i.e. where the confining radius is much smaller than the excitonic Bohr radius show discrete energy levels separated by several meV and are being considered as new gain media for laser applications. Using a very simple approach, one expects optical gain in quantum dots exactly at the energies of the ...
