| 英文摘要 | The molecular beam epitaxial growth and the optical properties of (1 1 2) b oriented hgte/hg1-xcdxte superlattices (sls) are compared with those of (0 0 1) orientated sls. first of all, the hg1-xcdxte barriers have a much higher cd concentration than those in (0 0 1) grown under similar conditions, i.e. x = 0.95 +/- 0.02 as opposed to x = 0.68 +/- 0.02 at a growth temperature of 180 degrees c. in addition the optical absorption edges are appreciably sharper than those in (0 0 1) oriented sls grown under similar conditions, by a factor of at least two. analogously, the full-width at half-maximum of the photoluminescence (pl) peak, e.g. 8 mev for a band gap of 100 mev at 4 k, is at least a factor of two narrower than that in our best (0 0 1) oriented sls. this can be explained by a more homogeneous growth laterally, i.e. in the plane perpendicular to the growth direction: either more homogeneous quantum well and barrier thicknesses or a more homogeneous interface width.
