Stable Low-Voltage Operation Top-Gate Organic Field-Effect Transistors on Cellulose Nanocrystal Substrates
No full textWe report on the performance and
the characterization of top-gate
organic field-effect transistors (OFETs), comprising a bilayer gate
dielectric of CYTOP/Al<sub>2</sub>O<sub>3</sub> and a solution-processed
semiconductor layer made of a blend of TIPS-pentacene:PTAA, fabricated
on recyclable cellulose nanocrystal–glycerol (CNC/glycerol)
substrates. These OFETs exhibit low operating voltage, low threshold
voltage, an average field-effect mobility of 0.11 cm<sup>2</sup>/(V
s), and good shelf and operational stability in ambient conditions.
To improve the operational stability in ambient a passivation layer
of Al<sub>2</sub>O<sub>3</sub> is grown by atomic layer deposition
(ALD) directly onto the CNC/glycerol substrates. This layer protects
the organic semiconductor layer from moisture and other chemicals
that can either permeate through or diffuse out of the substrate
