Light Emission by Group Four Semiconductors in Vertical Optical Resonators
Group Four (GF) semiconductors such as silicon, germanium and their alloys are the key materials of modern technologies for the electronic data processing. However, use of this class of materials for optoelectronic applications is hindered by the indirect nature of its band gap. The recent rise of direct band gap, group four alloys of the […] >>
