报告题目(中文)：3D原子探针在表征III-V族半导体纳米线中的应用
报告题目(英文)：Atomic-scale investigation of group III-V semiconductor nanowires grown by MOCVD
报告内容简介：The bottom-up seeded nanowires have been raising increasing attention for applications due to cost consideration, in contrast to the traditional subtractive manufacture i.e., lithography processing. It has been argued that the metallic seeds (such as Au, Ni,) is capable of absorbing the adatoms from ambient precursors and precipitating them out in the form of crystals at the metal/semiconductor interface. As a result, the nanowire can grow along either in-plane or out of plane direction with respect to their substrate orientation. However, the growth mechanism of seeded nanowires is quite complicated, often leading to an uncontrollable nanowire morphology and compositional distribution. Therefore, delicate characterization is only approach to link the property with their morphology, and also provide important evidence for quality nanowire growth. In this presentation, he will demonstrate the APT characterization results of the semiconductor nanowires from group III-V and assess the dopant within the nanowires.
