WebUsing scanning tunneling microscopy (STM) and spectrocopy (STS), chiral and ultra- narrow armchair GNRs and width-modulated GNR heterojunctions were studied. The local- ized edge states in chiral GNRs derived from unzipping carbon nanotubes were explored and evidence is shown that these states are spin-polarized. WebChiral model. In nuclear physics, the chiral model, introduced by Feza Gürsey in 1960, is a phenomenological model describing effective interactions of mesons in the chiral limit …
