Research on nanometer-thin pyrolyzed-carbon film on silicon nitride membrane is published
The new research paper by Justinas Jorudas et al. just recently was published in the journal Nanotechnology by IOP Publishing. The study reports on one of the first successful attempts to layer down the nm-scale-thick graphitic film on the wide-spectral-range transparent membrane. The results are promising in the field of development of broadband barometric radiation…
