(a) The transfer characteristics of the mono- (1L), bi- (2L), and tri-layer(3L) phosphorene TFETs for 15 nm channel length Lch. Transfer characteristics of constant electric field E scaling (i.e.
30 V/nm) for (b) 1L, (c) 2L, and (d) 3L phosphorene. For the Lch = 6 nm case, the Ids − Vgs can be optimized through asymmetric doping.
