On the stability of elastic nanoparticles

Abstract

Recent studies aimed at modification and destruction of metal nanoparticles via laser pulse and DC electric field treatment require careful analyses of charge and field instability of metal nanoparticles. Though the stability bounds of liquid drops are known well, the stability conditions of rigid nanoparticle surrounded by elastic media are still not clear. In this work we have revealed the boundaries of charge and electric field stability for rigid nanoparticles. Charge‐field stability bounds of silver nanoparticle embedded in glass.

Revealing the nanoparticles aspect ratio in the glass-metal nanocomposites irradiated with femtosecond laser

“…In our experimental conditions, one may expect the elongation of the nanoparticles caused by electrical forces at fluences above 0.625 J/cm 2 results in their partition with the formation of less elongated nanoparticles, which gives rise to the decreasing of aspect ratio at fluences between 0.625 J/cm 2 and 1 J/cm 2 . When we increase fluence higher a strong local electric field eventually destroys nanoparticles 15 29 similarly to their destruction by strong DC electric field 30 .…”
