- Аннотация: Two novel properties, unique for semiconductors: a negative electron affinity, and a high p-type surface electrical conductivity, were discovered in diamond at the end of the last century. Both properties appear when the diamond surface is hydrogenated. A natural question arises: is the influence of the surface hydrogen on diamond limited only to the electrical properties? Here, for the first time to our knowledge, we observe a transparency peak at 1328 cm-1 in the IR absorption of hydrogen-terminated pure (undoped) nanodiamonds. This new optical property is ascribed to Fano-type destructive interference between zone-center phonons and free carriers (holes) appearing in the near-surface layer of hydrogenated nanodiamond. This work opens the way to exploring the physics of electron-phonon coupling in undoped semiconductors and promises the application of the H-terminated nanodiamonds as a new optical material with an induced transparency in the infrared optical range.
