The thermo-optic nonlinearity of single metal nanoparticles under intense continuous-wave illumination
Ieng Wai Un, Yoatan Sivan
Over the last few decades, extensive previous studies of the nonlinear response of metal nanoparticles report a wide variation of nonlinear coefficients, thus, revealing a highly c…

Size-Dependence of the photothermal response of a single metal nanosphere
Ieng-Wai Un, Yonatan Sivan
We study the thermal response of a single spherical metal nanoparticle to continuous wave illumination as a function of its size. We show that the particle temperature increases no…
