Organisation profile
Silicon-germanium in the hexagonal crystal polytype has recently emerged as a new direct bandgap semiconductor promises to become the essential brick that was missing in the silicon industry. Hex-SiGe promises to integrate opto-electronic capabilities into the silicon industry. Research is directed towards a hex-SiGe laser, an optical amplifier, a detector as well as to low-dimensional hex-SiGe semiconductors like quantum wells and dots.
