The testing was carried out by the UK’s National Printable Electronics Technology Centre (PETEC) by incorporating SmartKem’s semiconductors into flexible thin film transistor (TFT) panels and assessed performance using a range of industry standard test methods. The device preparation was performed in ambient air indicating the excellent stability of this material ink formulation.

According to the manufacturer, the semiconductor materials excelled in testing and achieved a significant increase in TFT mobility performance over many other commercially available organic equivalents, across a range of transistor geometries. For example the average mobility across a range of devices at 30 µm channel length was recorded as 4.0 cm2 / Vs. Even more impressive was the short channel length performance with a recorded mobility of 2.5 cm2 / V at 4 µm.

SmartKem believes that the PETEC test results confirm these organic semiconductor materials are now aligned with the current and future performance requirements of printable transistors for the implementation of flexible drive electronics for display-based applications such as ePaper, HD-LCD and OLED.
