We investigate the practical limits of reliable charge detection in bistable molecules using a single-electron transistor (SET) as a sensor. To this end, we employ a metal-oxide SET integrated with a nanoscale dipole to mimic the molecule. Experimental data are supported by COMSOL and LT SPICE simulations to assess and optimize the sensing platform layout.
