Wigner Crystallization in a Quasi-3D Electronic System
B. A. Piot, Z. Jiang, C. R. Dean +4
When a strong magnetic field is applied perpendicularly (along z) to a sheet confining electrons to two dimensions (x-y), highly correlated states emerge as a result of the interpl…
Magneto-conductance Oscillations in Graphene Antidot Arrays
T. Shen, Y. Q. Wu, M. A. Capano +3
Epitaxial graphene films have been formed on the C-face of semi-insulating 4H-SiC substrates by a high temperature sublimation process. Nano-scale square antidot arrays have been f…
Observation of pinning mode of stripe phases of 2D systems in high Landau levels
G. Sambandamurthy, R. M. Lewis, Han Zhu +5
We study the radio-frequency diagonal conductivities of the anisotropic stripe phases of higher Landau levels near half integer fillings. In the hard direction, in which larger dc…
Pinning modes and interlayer correlation in high magnetic field bilayer Wigner solids
Zhihai Wang, Yong P. Chen, L. W. Engel +3
We report studies of pinning mode resonances in the low total Landau filling (ν) Wigner solid of a series of bilayer hole samples with negligible interlayer tunneling, and with var…
Microwave resonance of the reentrant insulating quantum Hall phases in the 1st excited Landau Level
R. M. Lewis, Yong P. Chen, L. W. Engel +3
We present measurements of the real diagonal microwave conductivity of the reentrant insulating quantum Hall phases in the first excited Landau level at temperatures below 50 mK. A…
AC Magnetotransport in Reentrant Insulating Phases of Two-dimensional Electrons near 1/5 and 1/3 Landau fillings
Yong P. Chen, Z. H. Wang, R. M. Lewis +5
We have measured high frequency magnetotransport of a high quality two-dimensional electron system (2DES) near the reentrant insulating phase (RIP) at Landau fillings () between…
