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 ...

Measuring the band gap of materials is vital in the nanomaterial, semiconductor, and solar industries. This article illustrates how the band gap of a material can be established from its UV absorption ...

Korean researchers have proved the existence of the second band gap in a 2D structure. The result is expected to be used in various fields such as the development of emerging materials, solar cells, ...

NIMS and the Tokyo Institute of Technology have jointly discovered that the chemical compound Ca 3 SiO is a direct transition semiconductor, making it a potentially promising infrared LED and infrared ...

Researchers in the US have the best evidence yet that the electronic band gap in bilayer graphene can be adjusted by changing an applied voltage. This is unlike conventional semiconductors such as ...
