We present a microscopic analysis of shot‐noise suppression due to long‐range Coulomb interaction in semiconductor samples operating between ballistic and diffusive transport regimes. We find that the strong suppression observed under the ballistic regime persists under quasi‐ballistic conditions, before being washed out when a complete diffusive regime is achieved.
