| Abstract Scope |
In recent times, heterojunctions of 1-D nanorods of transition metal oxides with n-type silicon have shown some peculiar electrical properties. Owing to such peculiarities, we investigate the electrical behavior of n-Si heterojunction with chemically synthesized h-MoO3 nanorods. To fabricate heterojunction, first, the nanorods were ground and suspended in a solution of ethanol and DI water followed by sonication in a water bath for 2 hours and centrifugation at 4000 rpm. The supernatants were collected. FESEM and XRD confirm the formation of h-MoO3 nanorods. Optical properties were characterized using UV-Visible spectroscopy. The collected supernatants were deposited over n-type silicon by spin coating at 1500 rpm for 15 seconds followed by the aluminium contact deposition. Room temperature current-voltage (IV) measurements of the heterojunction show a rectifying behavior with a rectification ratio of ̴12. This facile fabrication process paves the way for various low-cost applications especially in the field of sensing and photonics. |
