Examples of x, y, z manipulation, aberration correction and helical phase beams with increasing topological charge are shown in Fig. 5.
In addition, q-plates have been fabricated from liquid-crystal slabs to convert a left circularly polarized beam into a helically phased beam with right circular polarization, or vice versa [27].
Pd NPs are deposited on GCEs by using a gas phase cluster beam deposition technique.
The nanoparticle arrays were formed by gas phase cluster beam deposition and have the advantages of clean surface, good adhesion ability, and nice dispersion.
Pd nanoparticles with a mean diameter of 6.7 nm are prepared by gas phase cluster beam deposition.
It clearly indicates that the Pd NPs deposited by a gas phase cluster beam deposition process are comparatively small-sized and cause a nice dispersion, which results in a large specific surface area.
In this study, we use the gas phase cluster beam deposition process to fabricate Pd NP-deposited GCE (Pd NPs/GCE) and investigate the electrochemical properties of the fabricated electrodes in H2O2 sensing in detail.
Splitting of higher order topological charge has been done by the interference with three plane waves at smaller angle than the one which phase engineered beam makes with the axis.
Recently, it was demonstrated that Ag NP-deposited glassy carbon electrode (GCE), fabricated by means of gas phase cluster beam deposition, has the merits of high adhesion, good dispersity, as well as clean surface, owing to the high controllability on the size, coverage, and kinetic energy of the nanoparticles, and shows excellent catalytic activity in the electrochemical reduction of H2O2 [17].
Finally, the phase modulated beam is projected through a galvanoscanner for structuring control in X and Y axes and focused through a microscope objective.
