Unequal Layer Densities in Bilayer Wigner Crystal at High Magnetic Field
Zhihai Wang, Yong P. Chen, Han Zhu +4
We report studies of pinning mode resonances of magnetic field induced bilayer Wigner crystals of bilayer hole samples with negligible interlayer tunneling and different interlayer…
Observation of pinning mode in Wigner solid of 1/3 fractional quantum Hall excitations
Han Zhu, Yong P. Chen, P. Jiang +4
We report the observation of a resonance in the microwave spectra of the real diagonal conductivities of a two-dimensional electron system within a range of ~ +- .0.015 $ from fill…
Pinning mode resonance of a Skyrme crystal near Landau level filling factor =1
Han Zhu, G. Sambandamurthy, Yong P. Chen +5
Microwave pinning-mode resonances found around integer quantum Hall effects, are a signature of crystallized quasiparticles or holes. Application of in-plane magnetic field to thes…
Pinning mode resonances of 2D electron stripe phases: Effect of in-plane magnetic field
Han Zhu, G. Sambandamurthy, L. W. Engel +3
We study the anisotropic pinning-mode resonances in the rf conductivity spectra of the stripe phase of 2D electron systems (2DES) around Landau level filling 9/2, in the presence o…
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…
Dielectrophoresis model for the colossal electroresistance of phase-separated manganites
Shuai Dong, Han Zhu, J. -M. Liu
We propose a dielectrophoresis model for phase-separated manganites. Without increase of the fraction of metallic phase, an insulator-metal transition occurs when a uniform electri…
