people are working on nanowire solar cells, nanowire LEDS, nanowire FET.....
My question is that:
Is it a really good idea to use nanowire for making semiconductor devices.
Here are my arguments:
1. surface to volume ratio is so damn high for a nanowire.
2. Surface is a 2 dimensional defect, which creates electric field, non-
radiative combanation centers, unwanted energy states, etc. All these are
killers for semicondut | s*******e

Personally, I don't think there is any future of CNT to make devices unless
people can grow it with a good control of size and alignment that is
impossible for the way chemist doing.
The only way now is engineering, using semiconductor lithography
techniques to make, i.e., Si nano wire devices that had been demonstrated.

demosratation does not mean nanowire is a good solution.
