Abstract

Silicon and Germanium have an indirect band gap, which limits their use in optoelectronic devices Here, we show that we can create a direct band gap in Si_1-xGe_xalloys by changing the crystal structure from cubic to hexagonal. DFT calculations predict a strong optical transition for 0.65>x>1. Hex-Si_1-xGe_xalloys have been fabricated and efficient light emission has been observed.
