Alloy was used by the Inuit people. Native copper, however, was found worldwide, along with silver, gold, and platinum, which were also used to make tools, jewelry, and other objects since Neolithic times. Copper was the hardest of these metals, and the most widely distributed. It became one of the most important metals to the ancients. Eventually, humans learned to smelt metals such as copper and tin from ore, and, around 2500 BC, began alloying the two metals to form bronze, which was much harder than its ingredients. Tin was rare, however, being found mostly in Great Britain. In the Middle
Silicon-tin Silicon-tin Silicon-tin or SiSn, is in general a term used for an alloy of the form SiSn. The molecular ratio of tin in silicon can vary based on the fabrication methods or doping conditions. In general, SiSn is known to be intrinsically semiconducting, and even small amounts of Sn doping in silicon can also be used to create strain in the silicon lattice and alter the charge transport properties. Several theoretical works have shown SiSn to be semiconducting. These mainly include DFT-based studies. The band structures obtained using these works show a change in band gap of silicon with the
