Abstract:Current developments in the computing hardware are limited by the operating principles of CMOS technology: fabrication limits of sub-nanometer features and difficulties in the utilisation of the interconnects between chips. This set of obstacles has sparked a search for an alternative computing system. One of them is a computing approach utilising the material system. It was found that by using the physical property of the material itself, the computing method becomes more energy efficient[1]. This has been implemented in a nanoscale system based on a disor- dered system such as gold nanoparticles[2] or lowly doped silicons[3]. In this thesis, we attempt in evolving the lowly doped silicon chip using the interconnectivity between the chips. We first show the progress on how these experimental setups are developed with the chips, hardware, and the software interface. The experiments are done at the liquid nitrogen temperature using eight lowly doped silicon chips. The rudimental results show that interconnectivity may not be pow- erful enough to straightforwardly utilize in the genetic algorithm. As such, some suggestions are proposed in the end to further develop and investigate this multi-device system which can, with more optimisation, lead to a scaled-up functionality with the lowly doped silicon chips.
