Description
In recent times, van der Waals (vdW) dielectrics have gained momentum as essential components in condensed matter physics and advanced electronics. Compared to traditional amorphous dielectrics, vdW dielectrics provide atomically smooth surfaces, enhancing device performance and catering to the emerging field of two-dimensional (2D) electronics. However, the limited variety of these dielectrics and their low permittivity restrict the potential progress. Bismuth silicate, Bi2SiO5, emerges as a game-changer with a high out-of-plane dielectric constant and notable band gap. Its unique Aurivillius-type layered structure promises a breakthrough in applications necessitating ferroelectric and piezoelectric properties.This research pivots around harnessing Bi2SiO5's potential. Recognizing the current synthesis challenges and the limited exploration of ultrathin Bi2SiO5, our proposal centers on three pivotal objectives. First, refining Bi2SiO5 growth through chemical vapor deposition (CVD), considering the complexities of its synthesis. Second, delving deep into the dielectric properties of Bi2SiO5 and its integration with 2D semiconductors ensures a future-ready stance for upcoming transistor technologies. Lastly, unlocking the subtle piezoelectric and ferroelectric properties in ultrathin Bi2SiO5 layers, aiming at innovative applications in energy harvesting and memristive device development.Drawing on our proven track record in the CVD synthesis of emerging materials, integration of materials for advanced electronics, and expertise in the exploration of piezoelectric and ferroelectric properties, we are poised to bridge existing gaps in understanding and applying Bi2SiO5. Our research aims to provide a comprehensive understanding of Bi2SiO5's multifunctional capabilities, thereby shaping the future of low-power, high-performance electronic devices.Detail(s)
