Functional Structures of AgO_xThin Film for Near-Field Recording

Abstract

A general class of mass transport models with Q species of conserved mass is considered. The models are defined on a lattice with parallel discrete time update rules. For one-dimensional, totally asymmetric dynamics we derive necessary and sufficient conditions on the mass transfer dynamics under which the steady state factorizes. We generalize the model to mass transfer on arbitrary lattices and present sufficient conditions for factorization. In both cases, explicit results for random sequential update and continuous time limits are given.

Enhanced resolution induced by random silver nanoparticles in near-field optical disks

“…The distribution of the dissociated silver nanoparticles and clusters is very difficult to be observed directly. From experimental results, we found two possible distributions of the nanoparticles or clusters at the AgO x layer of the super-RENS [20]. The reading or recording focused laser beam drove the dissociated silver nanoparticles to form aggregative silver clusters or diffused ring structure.…”

The plasmon and distribution effects between incident light and active layer in PtOx-type super-resolution near-field structure

“…The nano-size Pt particles are embedded in the PtO x layer either by the fabrication process or by the photo dissociation process with incident laser light, and one can control the distribution of Pt nonoparticles and tend to the square distribution inside the active layer by adjusting the power of incident laser power as observed in our recent experiments [30]. If such a spatial distribution of materials within the super-RENS active layer that produces the desired results are able to find, it would enable us to model the super-RENS writing and reading process and to better understand the super-RENS phenomenon.…”

“…As we know, there are two different kinds of microstructures that can be produced in the AgO x mask layer by different input laser energies. 10 At a lower input energy, the centered silver dots could be formed with a high reflectance, while at a higher input energy, a ''nanoaperture'' ͑also called a cylinder or a ring͒ tended to be formed with a high transmission. Thus, the high readout power in our experiment indicated that the superresolution effect might be related to the formation of the nanoaperture.…”
