Robust fractional quantum Hall effect and composite fermions in the Landau level in bilayer graphene
Georgi Diankov, Chi-Te Liang, Francois Amet +9
The fractional quantum Hall (FQH) effect is a canonical example of electron-electron interactions producing new ground states in many-body systems. Most FQH studies have focused on…
Unconventional Correlation between Quantum Hall Transport Quantization and Bulk State Filling in Gated Graphene Devices
Yong-Tao Cui, Bo Wen, Eric Y. Ma +8
We report simultaneous transport and scanning microwave impedance microscopy to examine the correlation between transport quantization and filling of the bulk Landau levels in the…
An integrated capacitance bridge for high-resolution, wide temperature range quantum capacitance measurements
Joseph A. Sulpizio, Arash Hazeghi, Georgi Diankov +2
We have developed a highly-sensitive integrated capacitance bridge for quantum capacitance measurements. Our bridge, based on a GaAs HEMT amplifier, delivers attofarad (aF) resolut…
Facile Synthesis of High Quality Graphene Nanoribbons
Liying Jiao, Xinran Wang, Georgi Diankov +2
Graphene nanoribbons have attracted attention for their novel electronic and spin transport properties1-6, and because nanoribbons less than 10 nm wide have a band gap that can be…
Nanocrystal Growth on Graphene with Various Degrees of Oxidation
Hailiang Wang, Joshua Tucker Robinson, Georgi Diankov +1
We show a general two-step method to grow hydroxide and oxide nanocrystals of the iron family elements (Ni, Co, Fe) on graphene with two degrees of oxidation. Drastically different…
Simultaneous Nitrogen-Doping and Reduction of Graphene Oxide
Xiaolin Li, Hailiang Wang, Joshua T. Robinson +3
We develop a simple chemical method to obtain bulk quantities of N-doped, reduced graphene oxide (GO) sheets through thermal annealing of GO in ammonia. X-ray photoelectron spectro…
Criterion and Regions of Stability for Quasi-Equidistant Soliton Trains
V. S. Gerdjikov, E. G. Evstatiev, D. J. Kaup +2
Using the complex Toda chain (CTC) as a model for the propagation of the N-soliton pulse trains of the nonlinear Schrodinger (NLS) equation, we predict the asymptotic behavior of t…
