Researchers use 2D MoS2 to create transistors that can drive OLED displays

Researchers from Yonsei University managed to use a graphene-like 2D material called Molybdenum Disulfide (MoS₂) to create a transistor that can drive flexible OLED displays.

The researcher created a 6x6 OLED pixel array on a 7 mm plastic substrate that is so bendable (1 mm radius) it can be used as a skin sticker as can be seen in the video above.

The researchers say that up until now it was impossible to use MoS₂ as a transistor as the resistance between the material and the source and drain electrodes are too high. The new design, builds the transistor on AiO₃ layers, unlike the usually used SiO₂. This boosts the charge carrier mobility of the MoS₂ transistors.
