发帖数: 72 | 1 In the paper, basically the light is coupled out using a chemically etched
silica fiber. What's the technique of making the tip of the fiber about 100
nm? And how does he know the distance of the fiber tip to the sample?
Any one knows if it's possible to dope certain element at specific positions
of the nanowire? | l**********n

发帖数: 72 | 3 Maybe you can make sandwiched structure, like ABA and both A and B share the
same catalyst metal. There are many interesting things to think about, such as
how to improve the optical confinement, how to observe the dynamic response
from a single nanowire, how to do electronic pumping instead of optical
pumping.
Another question is that, is it possible to bend the nanowire when you grow
it?
