Extended Data Fig. 2

a-g, Chemical potential µ near ν = 1 measured with 0 mV (blue circles) DC bias applied to contact 3 and the best fit (red curves) using the skyrmion model by setting μm = 0 meV (see Methods) at 7 different locations. The values of EC obtained at these positions correspond to effective dielectric constants ε ranging from 10.0 to 12.4.
