Abstract
A procedure for composition optimization of mercury zinc telluride (Hg 1-xZnxTe) layers grown by isothermal vapor phase epitaxy (ISOVPE) is p resented. A quantitative model of mercury zinc telluride ISOVPE growth is proposed. The model is valid for temperatures between 450 and 600 degrees C and for solid HgTe source. A good agreement between experime ntal and calculated compositional profiles is obtained. Some peculiari ties of the ISOVPE Hg1-xZnxTe layers were analyzed using the presented model. A theoretical and experimental method for engineering of homog eneous MZT samples is proposed. The presented procedure can be used to tailor MZT epitaxial layers with desired properties, suitable for fab rication of infrared devices.
