Germanium's semiconducting, optical properties probed under pressure

Germanium may not be a household name like silicon, its group-mate on the periodic table, but it has great potential for use in next-generation electronics and energy technology. Of particular interest are forms of germanium that can be synthesized in the lab under extreme pressure conditions. However, until now one of the most-promising forms of germanium for practical applications, called ST12, has only been created in tiny sample sizes – too small to definitively confirm its properties.
