High carrier mobility and environmentally stable microporous zeolite imidazolate framework (ZIF-67): A field-effect transistor (FET) approach

Highlights: • The Zeolite Imidazolate Framework (ZIF-67) was successfully synthesized. • FET based on ZIF-67 exhibited p-type behaviour with highest hole mobility ~0.85 cm²/Vs and current Ion/off ratio 10². • ZIF-67 exhibited excellent environmental stability up to 40 days. The present investigation dealt with the synthesis of ZIF-67 and its exploration as an effective channel material for the applications based on Field-Effect Transistor (FET). The ZIF-67 was characterized by the spectroscopic, structural, morphological, thermogravimetric analyzer (TGA), and Brunauer–Emmett–Teller (BET) techniques. The transfer characteristics of ZIF-67 exhibits the p-type performance with hole mobility of ~0.85 cm²/Vs and the current I_on/off ratio 10². The fabricated FET device based on micro porous ZIF-67 exhibited excellent environmental stability up to 40 days.
