An investigation of mercury zinc telluride-cadmium telluride strained -layer superlattices grown by molecular beam epitaxy.

摘要

Hg;This work shows the first study of this superlattice system concentrating mainly on the study of the high hole and electron mobilities exhibited by some samples.;This strained-layer microstructure has been successfully grown with the molecular beam epitaxy technique. Samples have very high quality crystalline structure. Both p- and n-type samples have been obtained.;High hole mobility has been observed from Hall measurements in Type III superlattices and a further enhancement of hole mobility has also been noticed as the band gap ;Results are also consistent with those obtained from low field cyclotron resonance experiments. The interaction between the conduction and the first heavy hole subbands not only decreases the in-plane effective mass of HH
