Interlayer Correlated Quantum Hall States in Bilayer WSe₂

Recent advancements in the quality of transition metal dichalcogenide growth and contacts have enabled the measurement of the integer and fractional quantum Hall effects in monolayer WSe₂ devices. In contrast to monolayer WSe₂, the layer degree of freedom in bilayer WSe₂ creates a richer space for quantum Hall ground states including those with interlayer correlations. We will show transport measurements of the quantum Hall effect realized in high mobility WSe₂ bilayers and discuss the formation of quantum Hall states with interlayer correlation such as exciton condensates in the strong coupling limit.
