Abstract

The geometric and electronic structure of a C60 molecular layer on the Au(001) surfaces was studied by scanning tunneling microscopy and spectroscopy. The interaction between the substrate and overlayer is strong enough that the C60 monolayer is commensurate and uniaxially stressed along the 〈110〉 direction. As a result of stress the charge density around the C60 molecule appears to be deformed. Charge transfer was observed in ultraviolte photoemission spectroscopy and scanning tunneling spectroscopy, revealing the adsorption mechanism of the C60 molecule on this substrate.

APS and CERN Sign Open Access Agreement for SCOAP3

APS and CERN, the host organization of SCOAP3 (Sponsoring Consortium for Open Access Publishing in Particle Physics), have signed an agreement to make the high-energy physics (HEP) articles published in three leading APS journals open access beginning January 1, 2018. This agreement acts to support the publishing of open access content for wider benefit of the HEP community.
