文摘
- •
Electronic transport in individual polyacetylene chains is studied.
- •
Microwave emulation experiments and tight-binding calculations agree well.
- •
In long chains a band-gap opens due the dimerization of the chain.
- •
In short chains edge atoms cause strong resonance peaks in the center of the band-gap.
