“…Nanoscale devices, such as Si nanowire FETs (NWTs) [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 ] or graphene nanoribbon and carbon nanotube FETs [ 12 , 13 , 14 , 15 , 16 ], are promising transducers for the label-free detection of biological species. Both theoretical and experimental studies have predicted improvement of sensitivity (S) when scaling down NWTs dimensions.…”
