“…In such granular systems, metallic granules can be regarded as artificial atoms separated by insulating layers in sizes ranging from a few to hundreds of nanometers. By modifying the size or type of granules, the electronic transport of granular systems can be engineered, for example to achieve the enhanced Coulomb blockade [9] and the superconductor-insulator transition [10,11], enabling various application potentials [12,13].…”

Granular systems composed of metallic granules embedded as artificial atoms in the insulating matrix, have been extensively studied over the last decade due to their importance for nanotechnological applications and fundamental research on disordered materials. However, fabrication of uniform granular systems with tunable functionalities is still challenging. Here, from a nanoarchitectonic perspective, we proposed a general fabrication approach which exploits the different oxygen affinity between involving chemical elements to realize granular systems. Such a routine was demonstrated in the prototypical Mo-SiOx granular systems when the Mo-Si alloy target was sputtered at room temperature under oxygen-poor conditions. This growth approach produces highly disordered Mo-SiOx granular thin films, which exhibit the tunable electronic behavior, and huge photo-response (IL/ID up to 107 at 100 K), over 100% external quantum efficiency (in the wavelength range of 500 to 750 nm) and a short response time (~3 ms). Our work provides a new design principle for fabricating granular systems with tunable functionalities, which lays the foundation for understanding novel physical phenomena and rational design of multi-functional devices.

We consider discrete sine-Gordon equation on branched domains. The latter is modeled in terms of the metric graphs with discrete bonds having the form of the branched 1D chains. Exact analytical solutions of the problem are obtained for special case of the constraints given in terms of a simple sum rule. Numerical solution is obtained when the constraint is not fulfilled. A simple model of a Josephson junction network is proposed using the obtained results.
