Using a targeted computational approach, researchers in the Department of Materials Science and Engineering at Cornell have found more than 20 new self-assembled crystal structures, none of which had ...
By bringing together the right materials duking it out, a Cornell-led collaboration has for the first time used voltage to turn on and off a material’s crystal symmetry, thereby controlling its electr...
The mysterious changes in phases of matter – from solid to liquid and back again – have fascinated Eun-Ah Kim since she was in lower elementary school in South Korea. Without cold drinking water readi...
Perovskites hold promise for creating solar panels that could be easily deposited onto most surfaces, including flexible and textured ones. These materials would also be lightweight, cheap to produce,...

半导体性碳纳米管具有大长径比、无悬键表面、高载流子迁移率、室温弹道输运等独特结构特征和优异电学性质，因而被认为是十纳米以下高性能、低功耗晶体管沟道材料的有力候选。碳纳米管的导电属性取决于其螺旋（手性）结构，通常制备出的碳纳米管为金属性和半导体性碳纳米管的混合物。虽然近年来碳纳米管的结构控制生长与手性分离研究取得了较大进展，但单根碳纳米管的手性及导电属性调控仍是本领域研究的关键和难点。
