We consider massless three-dimensional N=1 supersymmetric quantum electrodynamics (QED) with Nf flavours of electrons. Within the dimensional reduction scheme, we compute critical exponents corresponding to both electron and selectron field (parity-even) mass anomalous dimensions at next-to-leading order in 1/Nf expansion an arbitrary covariant gauge. The equality gauge-invariant is found result from a subtle role played by epsilon-scalars. Our general framework also allows us pure scalar QED recover known results case spinor QED. An application our dynamical (s)electron generation considered. find evidence that, while flavor symmetry breaking occurs QED, remain interacting conformal phase.
