A Pt/Ir-coated Si tip was used as the Kelvin tip with a spring constant of 1–5 N m−1 and a resonant frequency of 60–100 kHz. To measure the surface potential under illumination, a 405 nm laser with a neutral density filter was used. The light intensity could be adjusted...
We would like to stress that the widely accepted mechanism—a cascadelike transfer of the energy by nonlinear Kelvin waves (and radiation of sound)—was not considered. One of the reasons is that the space resolution along the lines did not allow to detect generation of high harmonics, more...
a Chemically-Reacting Mixture The chemical reaction considered is the irreversible molecule-molecule dissociation of nitrogen N2 + N2 −−k→f 2N + N2 The rate coefficients are shown in Table 2 in which the units of A and Ta are given in m3·mol−1·s−1 and Kelvin, respectively. ...
