New Findings in Quantum Dots Described from Russian Academy of Science

June 10, 2014

By a News Reporter-Staff News Editor at Physics Week -- Data detailed on Quantum Dots have been presented. According to news reporting originating from Novosibirsk, Russia, by VerticalNews correspondents, research stated, "Hybrid structures consisting of InAs/AlGaAs quantum dots and In clusters on the surface separated by an AlGaAs spacer with a specified thickness are investigated. The enhancement of the photoluminescence signal in the long-wavelength region manifesting itself in the appearance of a new narrow emission line is observed."

Our news editors obtained a quote from the research from the Russian Academy of Science, "This line is absent in the control structure with a quantum-dot array and no metal clusters. It also disappears with increasing thickness of the dielectric spacer between the layers."

According to the news editors, the research concluded: "These results are explained in terms of a model taking into account the resonance interaction of excitons in quantum dots with localized surface plasmons in metal clusters."
