Synthesis and optical properties of multiband III-V semiconductor alloys
Abstract
Quaternary GaN<sub>x</sub>As<sub>1-y</sub>P<sub>y</sub> alloys have been synthesized using N ion implantation into GaAs<sub>1-y</sub>P<sub>y</sub> (y=0-0.4) epilayers followed by pulsed laser melting (II-PLM). We observed strong optical transitions from the valence band to both the lower (E <sub>-</sub>) and upper (E<sub>+</sub>) conduction subbands that arise from the N induced splitting of the conduction band (E<sub>M</sub>) of the GaAs <sub>1-y</sub>P<sub>y</sub> host. As predicted by the band anticrossing model, GaN<sub>x</sub>As<sub>1-xy</sub>P<sub>y</sub> with y>0.3 is a three band semiconductor alloy with potential applications for high-efficiency intermediate band solar cells. © 2007 American Institute of Physics.
