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…
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…
Evidence of a first order phase transition between Wigner crystal and Bubble Phases of 2D electrons in higher Landau levels
R. M. Lewis, Yong Chen, L. W. Engel +4
For filling factors in the range between 4.16 and 4.28, we simultaneously detect {\it two} resonances in the real diagonal microwave conductivity of a two--dimensional electron…
Wigner crystalization about =3
R. M. Lewis, Yong Chen, L. W. Engel +4
We measure a resonance in the frequency dependence of the real diagonal conductivity, Re[], near integer filling factor, . This resonance depends strongly on , with…
Correlation lengths of Wigner crystal order in two dimensional electron system at high magnetic field
P. D. Ye, L. W. Engel, D. C. Tsui +3
The insulator terminating the fractional quantum Hall series at low Landau level filling νis generally taken to be a pinned Wigner crystal (WC), and exhibits a microwave resonance…
