298 K (25 °C). Optically thick and morphologically flat polycrystalline Ag film, deposited by molecular beam epitaxy on a silicon wafer with a native oxide substrate.
The supplemental material of the original publication provides extra information by including additional data for 25 temperatures within the range of 298–600 K.
