Diamond is a wide-bandgap semiconductor (Egap = 5.47 eV) with tremendous potential as an electronic device material in both active devices, such as high-frequency field-effect transistors (FETs) and high-power switches, and passive devices, such as Schottky diodes.
What is the energy band gap between SiO2 and Y2O3?
From the analysis of O1s energy loss spectra, the energy band gap was determined to be 6.0±0.05 eV for Y2O3 and 8.9±0.05 eV for interfacial SiO2.
What is the optical band gap of hexagonal yfeo3?
As determined by diffuse reflectance spectroscopy (DRS) and Tauc plots, the hexagonal YFeO3 exhibits a lower optical band gap (1.81 eV) than the orthorhombic structure (about 2.1 eV or even higher) being typically obtained at elevated temperatures (>700 °C), and thus enables higher visible light photocatalysis activity.
What is the optical energy depth of a Y2O3 trap?
Photo (dis)charging experiments show that the optical energy depth of most of the traps exceeds 1.5 eV with respect to the Y2O3 conduction band, explaining the observed charge retention time of ∼ 108 s at room temperature, even in the absence of a blocking insulator. …
