Bridging the gap: Li1-xNaxAsS2 (x=0-1) species are found to be a new class of polar direct-gap semiconductors, which display a strong second harmonic generator (SHG) response. The anomalous band-gap trend and their direct-band-gap nature was studied by calculations. The 1.6 eV direct energy gap of LiAsS2 coupled with its high solubility makes it promising as an efficient light harvesting component in solar cells. (Graph Presented)
