dc.description.abstract
We investigate an electrostatically defined quantum point contact in a high-mobility InSb two-dimensional electron gas. Well-defined conductance plateaus are observed, and the subband structure of the quantum point contact is extracted from finite-bias measurements. The Zeeman splitting is measured in both in-plane and out-of-plane magnetic fields. We find an in-plane g factor |g^∗_∥|≈ 40. The out-of-plane g factor is measured to be |g^∗_⊥|≈ 50, which is close to the g factor in the bulk.
