One-dimensional InGaZnO field-effect transistor on a polyimide wire substrate for an electronic textile
Journal of the Korean Physical Society(2016)
摘要
Amorphous InGaZnO (IGZO) is a promising semiconducting material to replace amorphous and polycrystalline Si. IGZO-based field-effect transistors (FET) can be versatile platforms for various electronic or optoelectronic applications. Here, we report on a one-dimensional (1-D) IGZO FET fabricated on a flexible polyimide wire substrate for electronic textiles (e-textiles). This flexible 1-D IGZO FET shows a high mobility of 18.18 cm 2 /Vs with a relatively good on/off current ratio of 10 4 at operating voltages below 5 V. Furthermore, a resistive-load inverter is implemented by connecting the 1-D IGZO FET to an external load resistor. Such an inverter exhibits obvious voltage switching characteristics, verifying the potential it is being a basic building block for an e-textile circuit system.
