报告摘要：
When a wire is only a few nanometers wide, it may be called a
nanowire. Often benefited from their unprecedented dimensions,
nanowires are promising building blocks for various applications,
such as electronics, photonics and mechanics just to name a
few. Enormous research has been done in the past decade in nearly
every aspect on nanowires, from synthesis, structural
characterizations, surface chemistry, assembly to devices. Great
progress is made and exciting advancements are reported in a fast
pace. In this series of talks, I plan to share my research in this
area and try to provide a comprehensive overview. I'll focus on two
common semiconductor materials, silicon and germanium, and use them
as examples to introduce nanowire research in large. Owing to its
interdisciplinary nature, this line of research covers multiple
conventional disciplines: chemistry, physics, biology, engineering
and much more. Their applications and implications will also be discussed.
