摘要

We investigate temperature and nuence dependent dynamics of the photoexcited quasiparticle relaxation and low-energy electronic structure in electron-doped 1111-structure Sm(Fe_(0.93)Co_(0.07))AsO single crystal. We find that the behavior is qualitatively identical to the 122-structure Ba(Fe,Co)_2 AS_2 including the presence of a normal state pseudogap and a marked twofold symmetry breaking in the tetragonal phase that we relate to the electronic nematicity. The twofold symmetry breaking appears to be a general feature of the electron-doped iron pnictides.
