Direct bandgap quantum wells in hexagonal Silicon Germanium

Authors demonstrate the synthesis and characterization of direct bandgap quantum wells in the hexagonal Si_1−xGe_x system. Photoluminescence experiments show light emission up to room temperature, and the emission wavelength can be tuned by thickness of the wells and the Si composition.

Direct-bandgap emission from hexagonal Ge and SiGe alloys

A hexagonal (rather than cubic) alloy of silicon and germanium that has a direct (rather than indirect) bandgap emits light efficiently across a range of wavelengths, enabling electronic and optoelectronic functionalities to be combined on a single chip.
