We report a method to generate vortex filaments by nanosecond laser pulses at the interfacial shear layer of melted (silicon-oxynitride) SiON/Si as well as their selforganization (SO) into supercomplex (semi)conducting pattern of the neural network morphology. The laser beam homogenization with 210 beamlets generated the Si vortex filament network embeded into isolating SiON basis.
We studied the features of the network architecture such as branching pattern, branch-length distribution, and inter-filament crosslinks. Through the systematic varition of the number of pulses, the complexity level was varied showing gradual increase with increasing N. More detailed understanding has been attained about the role of the number of pulses (number of beamlets) on the structure, shape and the SO of filaments in the isolating SiON that constraints conformational freedom. The network architectures include star-branched, dendritic (fractal) randomly hyperbranched filaments as well as hellicaly paired, braided and tangled ones. The topological complexity originates from the crosslinking of neighbor filaments and the physical entanglement that are trapped and mimics polymer-chain linking and the neural network organization as well. Regularity and discrete structure indicate possibility for digitized function of such silicon vortex filament network.
