Wide angle high temperature analysis of MDPhC: a Before the furnace test, the absorption spectra of different angles were measured at room temperature; b RCWA simulates the contour plot of the absorption spectrum as a function of incident angle 8; c The absorption spectra of the arc sample stored in a furnace at 1000 ℃ for 24 h correspond to its SEM images obtained d before and e after the furnace test (Note that the ring is no longer visible due to the arc layer); SEM images of non-arc samples f before and g after; h SEM of section FIB of arc sample after furnace test (Degradation caused by metal surface diffusion (SD) and debonding (DET) showed that all scales were 200 nm) [96]
