  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.
