WebJan 18, 2007 · Amine and phenyl layers are very different with respect to formation, growth, thickness and molecular arrangement. We deduce a sub-monolayer of amine linker molecules on diamond with approximately 10% coverage of 1.5×10 15 cm −2 carbon bonds. Amine is bonded only on initially H-terminated surface areas. WebMar 3, 2016 · Basic features and mechanism of femtosecond laser graphitization of diamond surface were studied in the two regimes of irradiation: (1) by an intensive (>10 J/cm2) single shot and (2) by a train of pulses with near-threshold intensity (~1–10 J/cm2). Special attention was paid to the so-called accumulative regime, when multipulse laser … hakko authorized dealer
