Growth of epitaxial CdSe upon sapphire

Self Cite

Hetero‐epitaxial growth of CdSe on artificial mica (fluorflogopit, KMg3[Si3AlO10]F2), on (0001) sapphire and (111) Ge substrates has been investigated using the H2–CdSe vapour growth technique. The partial pressures of cadmium and selenium in the gas phase has been calculated for the different temperatures. The transport rate of the CdSe source and the growth rate of the epitaxial layers are theoretically and experimentally defined. A comparison between the experimental results and the thermodynamic model has been made. The structure and morphology of the layer surfaces are investigated.

The epitaxial growth of ZnSe on sapphire substrates

Epitaxial layers of ZnSe were grown on (0001) sapphire substrates using two techniques: hydrogen transport of ZnSe a t atmospheric pressure and vacuum sublimation in a quasiclosed space system. A comparison is made between these methods. The partial pressures of zinc in both t h e systems have been calculated for a wide range of temperatures. On t h e base of theoretical and experimental growth rates, the optimum technological conditions of the growth process are estimated. The structure and the surface morphology of the layers are presented. 3IIATaKCAaJIbHbIe CJlOkI CeJIeHMHa 4MHKa 6bIjIII BblpaueHbI Ha IIOJJIOXKaX CaII$IIpa C OpIIeHTaUMea (0001) C ACIlOJlb30BaHMeM ABYX MeTOiIOB : BOfiOPOJHbIii TPaHCIIOPT CeJIeHAHa UAHIla IIpA aTMOC$epHOM AaBJIeHMEl A BaHyJ' MHaR Cy6JrMMaUAJ€ B KBa3A-HLiH LWHKa B 06014~ CACTeMaX pac4HTaHbl EJIH UIApOHOfi 06nac~zi TeMnepaTyp.
