SmartKems novel organic semiconductor materials achieve “better than amorphous-silicon performance
Article Type: New products From: Microelectronics International, Volume 29, Issue 1
SmartKem Limited, the developer of novel, printable organic semiconductor materials and ink formulations for flexible electronics announced that its advanced semiconductor materials have achieved performance “better than amorphous-silicon” in recent testing, achieving an impressive thin-film transistor (TFT) mobility rating, higher than other traditional organic equivalents.
The testing was carried out by the UK’s national Printable Electronics Technology Centre (PETEC) by incorporating SmartKem’s semiconductors into flexible 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.
SmartKem’s advanced 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.
There is a strong drive in the electronics sector towards printable transistors that will enable low cost, portable devices such as thin-film TVs, lightweight smart phones and tablet PCs. Organic semiconductors can be used to fabricate lightweight, flexible electronics and are considered an exciting alternative to silicon semiconductors. Carefully formulated “inks” can be used to print circuits onto thin flexible substrates such as plastics and paper, enabling new form-factor electronics and radically simplifying the manufacturing process.
PETEC is a highly regarded technology institute, prototyping and characterising the performance of printable electronics, assisting businesses in the industry by testing and reporting on their processes in a production quality environment.
