The structural parameters and the pressures at which these compounds undergo structural phase transition from zinc-blende (B3) to the rocksalt (B1) are determined. From the results of the electronic properties we find that the parent materials (GaP, AlP) have indirect bandgaps. The resemblances between GaP and AlP and their small lattice mismatch led us to perform investigations on zinc-blende/zinc-blende for n=1,2 and 3 monolayer. Our calculations performed for band structure and density of state show an indirect band gap superlattices for n=1 and 2 and a direct band gap for n=3. Details of the electronic structure of superlattices are discussed. An excellent agreement was found between our results and those of other theoretical predictions and experimental measurements. 2011-02-07T09:33:31Z 2011-02-07T09:33:31Z 2011-02 Article Superlattices and Microstructures, vol. 49(2), 2011, pages 132-143 0749-6036 http://www.sciencedirect.com/science?_ob=MImg&_imagekey=B6WXB-51M0N91-2-H&_cdi=7154&_user=1659113&_pii=S0749603610002363&_origin=search&_coverDate=02%2F28%2F2011&_sk=999509997&view=c&wchp=dGLzVzb-zSkzS&md5=e8dac106cd47356fb3893100f4f45747&ie=/sdarticle.pdf http://hdl.handle.net/123456789/10768 en Elsevier Ltd.
