Description

By thermodynamical calculations of the vapour phase composition expected to occur in the closed - tube CVD of CdTe films on CdTe substrates, it is shown that a VLS growth mechanism should be active in the growth process when use is made of the thermal decomposition of NH4Cl for producing the proper amount of HCl as a transport agent. Responsible of this VLS mechanism is the liquid tellurium, which is always present when the NH4Cl concentration reaches values sufficiently high for the epitaxial deposition of CdTe films. (author)
