[0484] Fabrication and electrical characterization of organic field-effect transistors (OFET) based on compounds and polymers of the present invention

[0485] Preparation of back-contact, top-gate FETs

[0486] Semiconducting compound I-x or polymer Px is dissolved at a concentration of 0,75wt % in orthodichlorobenzene and subsequently coated onto a PET-substrate with lithographically prepatterned gold contacts, serving as Source and Drain contact of the FET. 100 μl of the formulation is coated by a standard blade coater at a coating speed of 20 mm/s, yielding a homogenous layer of the semiconductor over the entire substrate. After the coating is completed, the substrate is immediately transferred onto a preheated hotplate and heated for 30s at 90° C. Next the gate dielectric layer consisting of Cytop CTL-809M is spincoated on top of the organic semiconductor (1200 rpm, 30s). After Spincoating, the substrate is again transferred to the hotplate and annealed for another 5 Min at 100° C. The thickness of the dielectric layer is 535 nm measured by profilometer. Finally 50 nm thick shadow-mask patterend gold gate electrodes are deposited by vacuum evaporation to complete FETs in the BGTC-configuration (See FIG. 1a-h)

Electrical characterization

[0487] The mobility μ is calculated from the root representation of the transfer characteristic curve (solid grey curve) calculated in the saturation region. The slope m is determined from the dashed black line in FIG. 1. The dashed black line in FIG. 1 is fitted to a region of the root representation of the current characteristic ID such that a good correlation to the linear slope of the root representation is obtained.

[0488] The threshold voltage U.sub.Th can be taken from the intersection of black dashed line in FIG. 1 with the X-axis portion (V.sub.GS).

[0489] In order to calculate the electrical properties of the OFET, the following equations are employed:

[00001]$\mu =\frac{m^2*2.Math..Math.L}{C_G*W}$$C_G={\mathrm{.Math.}}_0*{\mathrm{.Math.}}_r.Math.\frac{1}{d}$$U_{\mathrm{Th}}=-1*\frac{m}{b}$$\mathrm{ON}.Math.\text{/}.Math.\mathrm{OFF}=\frac{I_D.Math.\max }{I_D.Math.\min }$

[0490] where ε.sub.0 is the vacuum permittivity of 8.85×10.sup.−12 As/Vm. ε.sub.r=2,1 for Cytop and d=535 nm is the thickness of the dielectric. With the channel length L=10 μm and the channel width W=250 μm.

[0491] The following mobilities have been calculated for the respective compounds:
