With the growing use of wireless electronics systems, off-state leakage current in MOSFETs appears as one of the major physical limitations. Measurements of quantum tunnel current between source-drain (S?D) have recently shown that it will become detrimental in bulk MOSFET architecture for channel length around 5nm and at low temperature (£100K). After a careful validation of quantum drift-diffusion model (QDDM), we present a systematic study of the impact of source-drain direct tunnelling on off-state leakage current in double-gate MOSFET architectures. A large range of temperature (100K<T<Lc<tsi
