2024 IEEE Symposium on VLSI Technology and Circuits (VLSI Technology and Circuits)
Year: 2024 | Conference Paper |
We present record-low equivalent oxide thickness (EOT) of 2.4 Å with a remarkable dielectric constant (K) of 64 at 4.1nm-thick hafnium-based films with no wake-up characteristics. In comparison to conventional HZO films, our remarkable achievement stems from the high-quality crystalline structure with less oxygen vacancies formed by a low-damage process, as evidenced by high-angle annular dark-fie...Show More

2017 IEEE 12th International Conference on Nano/Micro Engineered and Molecular Systems (NEMS)
Year: 2017 | Conference Paper |
we report on ZnO nanorods based acoustic transducer for sound pressure level sensing applications. The sensing element is a circular diaphragm (diameter: 27 mm) of Stainless steel (SS-304L) substrate, which also acts as a bottom electrode for the developed transducer. Prior to synthesis of nanorods, ZnO seed layer (∼100 nm) film was deposited by DC magnetron sputtering technique. ZnO nanorods were...Show More
