    Light Absorbing Diamond for Solar Energy Conversion

    High-temperature solar cells are possible by exploiting the Photon-Enhanced Thermionic Emission (PETE) concept, which represents a novel and very attractive mechanism for the exploitation of solar radiation, e...

    Optical properties of femtosecond laser-treated diamond

    A laser-induced periodic surface structure (LIPSS) has been fabricated on polycrystalline diamond by an ultrashort Ti:Sapphire pulsed laser source (λ = 800 nm, P = 3 mJ, 100 fs) in a high vacuum chamber (<10−7 mb...

    Raman investigation of femtosecond laser-induced graphitic columns in single-crystal diamond

    We report on the fabrication of graphitic columns induced in single-crystal diamond plates using 100 fs laser pulses at 800 nm wavelength. Different values of laser fluence (0.6–1.2 J/cm2) and graphitization spee...
