Lists of metalloids the literature can also be found to the categorisation of other elements as metalloids. These elements include: hydrogen, nitrogen, sulfur, zinc, gallium, iodine, lead, and radon (citations are for references other than those listed above). Lists of metalloids This is a list of sources that each list metalloids: elements classified as metalloids. The sources are listed in chronological order. Lists of metalloids differ since there is no rigorous definition of metalloid (or its occasional alias, 'semi-metal'). Individual lists share common ground, with variations occurring at the margins. The elements most often regarded as metalloids are boron, silicon, germanium, arsenic, antimony
Germanium-tin have already been demonstrated. In addition, germanium-tin light emitting diodes operating at room temperature have also been reported. Germanium-tin Germanium-tin is an alloy of the elements germanium and tin, both located in group 14 of the periodic table. It is only thermodynamically stable under a small composition range. Despite this limitation, it has useful properties for band gap and strain engineering of silicon integrated optoelectronic and microelectronic semiconductor devices. Germanium-tin alloys must be kinetically stabilized in order to prevent decomposition. Therefore, low temperature molecular beam epitaxy or chemical vapor deposition techniques are typically used for their synthesis. Germanium-tin alloys have
