Table 2 Device characteristics of OFETs with hybrid dielectrics

From: Hybrid dielectrics composed of Al₂O₃ and phosphonic acid self-assembled monolayers for performance improvement in low voltage organic field effect transistors

Dielectric	Contact angle (º)	μ_sat (cm²/Vs)	SS (mV/decade)	V_Th (V)	I _on /I _off
Al₂O₃	< 10	0.05	345	− 2.18	~ 10⁵
HPA	102	0.35	151	− 1.71	~ 10⁶
DDPA	105.5	0.41	173	− 1.83	~ 10⁶
ODPA	109.8	0.58	135	− 1.84	~ 10⁶
PHDA	25.9	0.02	493	− 2.35	~ 10⁴
MDPA	65.1	0.05	197	− 1.64	~ 10⁵
PFPA	102	0.27	198	− 0.58	~ 10⁶
HUPA	28.5	0.03	196	− 1.95	~ 10⁵

The contact angle (º), saturation field effect mobility μ_sat (cm²/Vs), subthreshold slope SS (mV/decade), threshold voltage V_Th (V), on–off current ratio I_on/I_off
μ_sat (cm²/Vs), SS (mV/decade), V_Th (V) and I_on/I_off were calculated
