Abstract: R41.00013 : Design Method for a Phenalenyl-Tessellation Molecule Based Nano-Graphene Network with Coexisting Localized Zero Modes and Dirac Zero Modes*
10:24 AM–10:36 AM
Recently, we have discovered a class of graphene nano-molecular structures which we call Phenalenyl-Tessellation Molecule (PTM) with vacncies. When a PTM contains atomic defects, there appear two types of special non-bonding molecular orbitals at the zero-energy level. One is LZM and the other is DZM. Considering a Vacancy-centered hexagonal Armchair Nano-Graphene (VANG) as a typical example of a PTM, one LZM and one DZM appear non-trivially, and they form a singlet[2,3].
In this presentaton, we report a general rule for the appearance of the LZMs and DZMs in a class of PTM-based poly-aromatic hydro carbon. Our rule is indispensable for designing quantum information devices using zero modes in decorated defective graphene with vacancies.
