Model calculations of current and density distributions in dissipative Hall bars
… calculated density profile. The existence of "incompressible strips" with integer Landau level filling factor is investigated within a Hartree-type approximation, and nonlocal effects on the conductivity along those strips are simulated by a suitable averaging procedure. This allows us to …

Subsurface Charge Accumulation imaging of the quantum Hall liquid
… We proceed by imaging low compressibility strips in the presence of an artificially created density gradient in the 2DES. We study them in detail at Landau level filling factors v = 2, 4. The strips appear significantly wider than predicted by theory and we account for the discrepancy by …
