We address thermal and strength phenomena occurring in metal nanoparticles due to excitation of surface plasmons. The temperature of the nanoparticle is found as a function of the plasmon population, allowing for the Kapitza heat boundary resistance and temperature dependencies of the host dielectric heat conductivity and the metal electrical conductivity. The latter is shown to result in the positive thermal feedback which leads to appearance of the maximum possible number of plasmon quanta in the steady-state regime. In the pulsed regime the number of plasmon quanta is shown to be restricted from above also by the ponderomotive forces, which tend to deform the nanoparticle. Obtained results provide instruments for the heat and strength management in the plasmonic engineering.
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
