Z. Jaksic et al., COMPOSITION PROFILES VERSUS GROWTH PRESSURE AND TEMPERATURE IN EPITAXIAL HGZNTE LAYERS, Physica status solidi. a, Applied research, 152(2), 1995, pp. 451-459
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.
