Investigating Optical Properties of Oxide Materials at High Temperature

Grants and Contracts Details


This project will explore the optical properties of various oxide thin-films and crystals when they are exposed to high temperatures. Many oxide materials such as dielectrics and ferroelectrics are used as key components in electronic devices. However, their optical properties have not been studied in extreme environments even though their chemical stabilities at high temperatures are relatively well-known. This lack of knowledge can put space missions at an unexpected risk. For example, oxide components, which are optically transparent at room temperature (~22 °C) on Earth, may not be transparent at the surface temperature on Venus (~460 °C) due to changes in the optical bandgap energies. Hence, it is important to establish a substantial database of optical properties by investigating widely used oxide thin-films and crystals at various high temperatures. Further, this project will highlight novel dielectric and ferroelectric materials that may have enhanced optical properties in these extreme conditions.
