Transmission vs Energy
Common materials used for zone plates include gold (Au) and nickel (Ni), typically deposited through electroplating processes that require a seed layer—usually 5–20 nm thick and made of chromium or gold. Other materials such as chromium (Cr), ruthenium (Ru), molybdenum (Mo), diamond, silicon dioxide (SiO₂), and PMMA are also used, often fabricated via etching or direct writing methods that do not require a seed layer.
For hard X-ray applications, central zero-order beam stops can either be fabricated directly onto the substrate or precisely aligned and bonded onto the chip.
