    • The conductance is four orders of magnitude lower than it would be without tip passivation. The measured conductance with tip passivation is 180 nS with a variation of ±5%.

    • Whereas a strong anisotropy in phonon excitation in decagonal quasicrystals is predicted theoretically, only weak dependences were observed experimentally by inelastic neutron scattering (33).
