Spectral Fingerprints of Resonant Defect Scattering by Substitutional Mn in Graphene
Ahmed Samir Lotfy, Zviadi Zarkua, Renan Villarreal +10
Using substitutional Mn in graphene/Cu(111) as a model point defect, we combine scanning tunneling microscopy (STM) and angle-resolved photoemission spectroscopy (ARPES) to test th…
Unravelling the Band Structure and Orbital Character of a -Conjugated 2D Graphdiyne-Based Organometallic Network
Paolo D'Agosta, Simona Achilli, Francesco Tumino +7
Graphdiyne-based carbon systems generate intriguing layered sp-sp organometallic lattices, characterized by flexible acetylenic groups connecting planar carbon units through me…
Electronic Structure Shift of Deep Nanoscale Silicon by SiO- vs. SiN-Embedding as Alternative to Impurity Doping
Dirk König, Noël Wilck, Daniel Hiller +7
Conventional impurity doping of deep nanoscale silicon (dns-Si) used in ultra large scale integration (ULSI) faces serious challenges below the 14 nm technology node. We report on…
Origin of the flat band in heavily Cs doped graphene
N. Ehlen, M. Hell, G. Marini +6
A flat energy dispersion of electrons at the Fermi level of a material leads to instabilities in the electronic system and can drive phase transitions. Here we introduce a method t…
Narrow photoluminescence peak of epitaxial MoS on graphene/Ir(111)
Niels Ehlen, Joshua Hall, Boris V. Senkovskiy +10
We report on the observation of photoluminescence (PL) with a narrow 18 meV peak width from molecular beam epitaxy grown MoS on graphene/Ir(111). This observation is explained…
