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…
