0072110MenendezThis three-year award will provide support for Jose Menendez of Arizona State University to work with Jose Calleja at the Universidad Autonoma de Madrid, Spain. The primary goal of their research is to perform inelastic light scattering studies of carbon nanotubes under high magnetic fields, in the expectation of characterizing nanotube samples, which always contain a heterogeneous distribution of nanotube sizes and structures. In addition, they plan to investigate some unusual magnetic field effects - ranging from a metal-insulator transition to an enhancement of the predicted Peierls distortion in 1D-metals -- that have been predicted theoretically.The two laboratories are complementary. The US laboratory is equipped with Raman instrumentation with extremely high resolution and contrast. The Spanish laboratory is one of the few in the world where Raman measurements with fields as high as 12T and temperatures as low as 0.3 K can be performed routinely. Carbon nanotubes have been proposed as the ideal tip materials for scanning probe microscopies, as an alternative to composite

0072110Menendez 这个为期三年的奖项将为亚利桑那州立大学的 Jose Menendez 与西班牙马德里自治大学的 Jose Calleja 合作提供支持。 他们研究的主要目标是在高磁场下对碳纳米管进行非弹性光散射研究，以期表征纳米管样品，这些样品始终包含纳米管尺寸和结构的异质分布。 此外，他们还计划研究一些不寻常的磁场效应——从金属-绝缘体转变到一维金属中预测的 Peierls 畸变的增强——这些效应已经在理论上得到了预测。这两个实验室是互补的。 美国实验室配备了具有极高分辨率和对比度的拉曼仪器。 西班牙实验室是世界上少数几个可以常规进行高达 12T 场强和低至 0.3 K 温度拉曼测量的实验室之一。 碳纳米管已被提议作为扫描探针显微镜的理想尖端材料，作为复合材料的替代品
