| contents | Nonlinear electrical conduction primarily mediated by an orbital texture is observed in chiral semiconductor Te. We determine the enantiospecific sign of the nonlinear conductance and identify anomalies in its carrier-density dependence. Our findings, combined with the Boltzmann equation, are attributed to a chiral orbital texture, namely a chiral distribution of the orbital magnetic moment in reciprocal space. This study underscores the efficacy of nonlinear transport measurements in probing orbital-related effects, whose differentiation from spin counterparts is often demanding in the linear response regime of electron transport. |
