The inherently absent 2-dimensional electron gas in ultra-pure GaN/AlGaN heterostructures
S. Schmult, S. Wirth, V. V. Solovyev +5
Gallium nitride (GaN) has emerged as an essential semiconductor material for energy-efficient lighting and electronic applications owing to its large direct bandgap of 3.4 eV. Pres…
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…
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…
Tuning Negative Differential Resistance in a Molecular Film
M. Grobis, A. Wachowiak, R. Yamachika +1
We have observed tunable negative differential resistance (NDR) in scanning tunneling spectroscopy measurements of a double layer of C60 molecules on a metallic surface. Using a si…
