Dielectric Solution Characteristics
Materials PerformanceCapacitance 7 – 8 nF/cm2
Thickness After Cure 400 – 700 nmSurface Roughness < 10 nm
Xerox dielectric material is a solution processable dielectric ink which yields uniform thin films exhibiting high capacitance.
Technology • Solution coatable and printable dielectric with
demonstrated performance in bottom-gateorganic thin film transistors
• High on/off ratio and low hysteresis observed whenpaired with a CNT or polymer semiconductor in TFTs
• Low surface roughness, pinhole free filims formed• Compatibile with Xerox silver nanoparticle inks
(xcm-nsIJ-RS1, xcm-nsPA-RS1)
Test samples were prepared by spin coating xdi-dcs (2000 rpm, 60 s) onto a conductive substrate. The sample was dried at 80 °C for 10 minutes, and cured at 140 °C for 30 minutes. 60 nm gold electrodes were evaporated onto the cured dielectric.

Printing ConditionsAerosol Jet: Traces were printed on PC substrates using an Optomec Sprint system with a pneumatic atomizer. Stablemass output was achieved using the following conditions: 250 µm nozzle, 150 sccm sheath gas, 75 sccm push gas (N2).
Inkjet: Traces were printed using a Dimatix DMP 2800printer. 5 ng drops with drop velocity of 3 m/s at avoltage of 23 V with a 40 µm drop spacing were deposited on glass subtrate.
