0242579PhaneufThis three-year award provides support for Raymond Phaneuf of the University of Maryland to work with Roberto Cingolani of the University of Lecce, Italy. The primary goal of their research is to investigate the coupling of self-assembled quantum dots in the InxGa1-xAs/GaAs system. They plan to accomplish self-assembly and to control coupling of small numbers of dots, and to selectively probe individual coupled-quantum dot molecules.The two laboratories have complementary capabilities. The US laboratory will compare results for thin stressor layers grown on patterned substrates with those for lithographically produced arrays of alloy mesas to pattern the surface before regrowth. Parallel investigations using patterning and MOCVD growth will be carried out at Lecce. The Italian laboratory has developed the technique of using scanning tunneling luminescence to selectively probe individual coupled-quantum dot molecules. Existing applications of self-assembled quantum dots include optoelectronic devices such as quantum dot lasers. A potentially important application is the use of coupled quantum dots and qubits for quantum information processing.

0242579 Phaneufthis三年奖项为马里兰州大学的雷蒙德·法纳夫（Raymond Phaneuf）提供了支持，以与意大利Lecce大学的Roberto Cingolani合作。他们研究的主要目的是研究INXGA1-XAS/GAAS系统中自组装量子点的耦合。他们计划完成自组装并控制少量点的耦合，并有选择地探测单个耦合 - 量子点分子。这两个实验室具有互补的能力。 美国实验室将比较在图案化的底物上生长的薄应激层的结果，并将其用于印刷形成的合金台面阵列的结果进行比较，以在再生之前对表面进行图案。 使用图案和MOCVD生长的平行研究将在LECCE进行。意大利实验室已经开发了使用扫描隧道发光来选择性探测单个耦合量子点分子的技术。 自组装量子点的现有应用包括光电设备，例如量子点激光器。 潜在的重要应用是使用耦合的量子点和Qubits进行量子信息处理。
