#361 What’s wrong/good with tin?

Tin (Sn) is an element in group IV of the Periodic Table often referred to as “semiconductor group” for the reason that it includes elements displaying semiconductor properties. However, unlike other elements in group IV, notably carbon, (C), silicon (Si), and germanium (Ge), characteristics of tin are not conducive with the needs of semiconductor device technology. The two key reasons are an extremely narrow energy gap (effectively close to 0 eV) and its low melting point of 223 oC making tin hardly compatible with mainstream semiconductor device manufacturing practices. As the results tin is primarily used as solder.


While elemental thin in either bulk or thin-film form is not of use in semiconductor device technology, tin combined with other elements to form compounds as well tin in 2D (2-dimensional) form seem to display a number of potentially attractive characteristics. More about it next time…
