Tuning fulleride electronic structure and molecular ordering via variable layer index
Yayu Wang, Ryan Yamachika, Andre Wachowiak +2
C60 fullerides are uniquely flexible molecular materials that exhibit a rich variety of behavior, including superconductivity and magnetism in bulk compounds, novel electronic and…
Novel Orientational Ordering and Reentrant Metallicity in KxC60 Monolayers for 3 <= x <= 5
Yayu Wang, R. Yamachika, A. Wachowiak +5
We have performed local STM studies on potassium-doped C60 (KxC60) monolayers over a wide regime of the phase diagram. As K content increases from x = 3 to 5, KxC60 monolayers unde…
Spatially-resolved electronic and vibronic properties of single diamondoid molecules
Yayu Wang, Emmanouil Kioupakis, Xinghua Lu +6
Diamondoids are a unique form of carbon nanostructure best described as hydrogen-terminated diamond molecules. Their diamond-cage structures and tetrahedral sp3 hybrid bonding crea…
Phase Separation and Charge Transfer in a K-doped C60 Monolayer on Ag(001)
M. Grobis, R. Yamachika, A. Wachowiak +2
We have performed a scanning tunneling microscopy and spectroscopy study of potassium-doped C60 monolayers (KxC60) on Ag(001) in the regime of x ~ 1. Low temperature annealing (640…
Scanning tunneling spectroscopy of inhomogeneous electronic structure in monolayer and bilayer graphene on SiC
Victor W. Brar, Yuanbo Zhang, Yossi Yayon +6
We present a scanning tunneling spectroscopy (STS) study of the local electronic structure of single and bilayer graphene grown epitaxially on a SiC(0001) surface. Low voltage topo…
Observing Spin Polarization of Individual Magnetic Adatoms
Y. Yayon, V. W. Brar, L. Senapati +2
We have used spin-polarized scanning tunneling spectroscopy to observe the spin-polarization state of individual Fe and Cr atoms adsorbed onto Co nanoislands. Both of these magneti…
