Download scientific diagram | Transmission from far infrared to visible. In the far infrared, pro- nounced absorption lines due to vibrations in the silicon dioxide membrane are observed. The transmission in the visible is quasi-zero as major parts of the light are diffracted at the entrance of the pores toward the absorbing pore walls. Inset: Increase of transmission for very short wavelengths due to reduced diffraction. from publication: Macroporous silicon membranes as electron and x-ray transmissive windows | Macroporous silicon membranes are fabricated whose pores are terminated with 60 nm thin silicon dioxide shells. The transmission of electrons with energies of 5 kV –25 kV through these membranes was investigated reaching a maximum of 22% for 25 kV . Furthermore, the | Membranes, Silicon and Transmission | ResearchGate, the professional network for scientists.
