For the first time, the authors have investigated the analysis of the room‐temperature operation of single‐electron transistor (SET) for periodic symmetric functions (PSFs). They demonstrate that in SETs due to the Pauli exclusion principle the distance between current peaks against bias voltage in coulomb oscillations will be asymmetric. Also, because the separated energy levels have unequal tunnel‐barrier resistance, different tunnelling current rates are obtained for each level. So, the unequal peak‐to‐valley current ratio (PVCR) will be observed in the coulomb oscillations, and therefore the operation of room‐temperature of silicon SET‐based PSFs is impossible.
