Keywords: | DRNTU::Science::Chemistry::Physical chemistry | Issue Date: | 2012 | Source: | Gupta, R. K., Ying, G., Srinivasan, M. P., & Lee, P. S. (2012). Covalent assembly of gold nanoparticles: an application toward transistor memory. The journal of physical chemistry B, 116(32), 9784-9790. | Series/Report no.: | The journal of physical chemistry B | Abstract: | This work reports a versatile approach utilizing covalent assembly of functionalized gold nanoparticles for organic field-effect transistor (OFET) based memory devices. 11-Mercapto-1-undecanol functionalized gold nanoparticles (AuNPs) having size of 5 ± 0.5 nm were synthesized and immobilized onto SiO2 substrate through covalent binding using a functionalized polymer as a surface modifier. The pentacene OFET-based memory devices utilizing such covalently bound gold nanoparticles with nanoparticle density of 5 × 1011 cm–2 exhibited a large memory window (7.7 V), high on/off ratio between memory states (105), and long retention time (>10 000 s). The present synthetic route for memory devices incorporating covalently immobilized gold nanoparticles has several advantages such as solution processable, enhanced device stability, low-cost, and low-temperature process and will be a step toward realization for low-cost, lightweight, flexible, logic display driver, and flash memory applications. | URI: | https://hdl.handle.net/10356/96170 http://hdl.handle.net/10220/17120 |
