Table 1. Electrical characteristics of the devices with different channel lengths

Channel length (μm)	Von (V)	Vth (V)	Imax/Imin	Subthreshold swing (V/dec)	Field effect mobility (cm2/Vs)*
100	−76	−28.9	4.8×106	5.07	48.2
150	−64	−24.1	6.4×106	1.65	50.7
200	−40	−13.3	2.0×106	1.60	46.1
250	−42	−11.5	1.6×106	1.56	53.8

Please note that the field effect mobility values are calculated by utilizing effective channel length L_eff in Eq. 2.
