Abstract

Separate nanoholes with the minimum size down to 35 nm (λ/15) and nanohole arrays with the hole size about 100 nm (λ/5) were fabricated in a 50 nm optically “thick” Au/Pd film, using single 532 nm pump nanosecond laser pulses focused to diffraction-limited spots by a specially designed apertureless dielectric fiber probe. Nanohole fabrication in the metallic film was found to result from lateral heat diffusion and center-symmetrical lateral expulsion of the melt by its vapor recoil pressure. The optimized apertureless dielectric microprobe was demonstrated to enable laser fabrication of deep through nanoholes.

  16. The thermal conductivity coefficient of Au κ(300  K)=317  Wm−1 K−1 [15] decreases by 5.3 times upon its alloying with Pd (20 wt. %), while at the Au melting temperature Tmelt,Au≈1337  K such reduction occurs by 2.5 times. Moreover, due to phonon scattering on its nanocrystallites, similar 50 nm thick Au film on a quartz substrate is known to demonstrate twice-lower thermal conductivity. As a result, for the weak temperature dependences of the Au heat capacity (Cp≈0.13  J/(gK)) [15] and mass density (ρ≈17.3  g/cm3), its thermal diffusivity χ=κ/(ρCp)) decreases overall by 5 (0.28  cm2/s) or 10.6 (0.13  cm2/s) times at 1337 or 300 K, respectively. Hence, over the 5 ns laser pulse the molten Au/Pd film provides heat conduction over the characteristic 1/e length σT≈1.55  μm.
