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…
