Ferromagnetism and conductivity in atomically thin SrRuO3
H. Boschker, T. Harada, T. Asaba +13
Atomically thin ferromagnetic and conducting electron systems are highly desired for spintronics, because they can be controlled with both magnetic and electric fields. We present…
Direct measurement of discrete valley and orbital quantum numbers in a multicomponent quantum Hall system
B. M. Hunt, J. I. A. Li, A. A. Zibrov +8
Strongly interacting two dimensional electron systems (2DESs) host a complex landscape of broken symmetry states. The possible ground states are further expanded by internal degree…
Sharp Tunneling Resonance from the Vibrations of an Electronic Wigner Crystal
Joonho Jang, Benjamin Hunt, Loren N. Pfeiffer +2
Photoemission and tunneling spectroscopies measure the energies at which single electrons can be added to or removed from an electronic system. Features observed in such spectra ha…
Observation of Helical Edge States and Fractional Quantum Hall Effect in a Graphene Electron-hole Bilayer
J. D. Sanchez-Yamagishi, J. Y. Luo, A. F. Young +5
A quantum Hall edge state provides a rich foundation to study electrons in 1-dimension (1d) but is limited to chiral propagation along a single direction. Here, we demonstrate a ve…
