The Adsorption and Conductivity of Silicon in Elastic Polymers

Silicon (Si) is the primary material of semiconductor elements. For semiconductor element production, Si is to be refined into high-purity silicon crystals with the approximate characteristics of intrinsic semiconductor, then doping 13^th group or 15^th group trace element. Producing high-purity silicon crystals with a good lattice structure requires a lot of energy and is costly. Besides its high purity, silicon is very hard and fragile, which limits its scope of application. For this reason, this study added low-grade, non-complete lattice silicon in the elastic polymer and then doped it with high concentrations of fine carbon powder. This material can be conductive by physisorption; therefore, it can be used to make semiconductors. Using this material to produce electronic components can significantly reduce the cost of purification and crystallization, saving energy simultaneously. Moreover, this elastic polymer material contains silicon, which has soft, warm and durable physical properties. With those properties, the device's design could be more flexible, fully scalable, and close to the skin.
