Extended Data Fig. 2: Longitudinal resistance of the high-mobility SPSL-grown heterostructure.

From: Observation of half-integer thermal Hall conductance

Extended Data Fig. 2

Longitudinal resistance measured in a Hall bar 100 µm wide and 200 µm long. Fractional filling factors are more pronounced than in the δ–Si-doped structure. Yet, the structure suffers from added thermal conductance in the bulk (see main text).
