Growth of CdTe/HgTe Superlattice with the LADA (Laser Assisted Deposition) Technique.

Abstract

Growth of HgTe/CdTe has been demonstrated by the laser assisted deposition technique (LADA). HgTe and CdTe compounds were used as sources. Multilayered structures were deposited by scanning a pulsed laser beam alternately over these sources. Superlattice parameters such as composition and period thickness were controlled by the scanning mode of a focused laser beam. The superlattices were characterized optically and electrically. Effect of band narrowing due to superlattice formation was observed. (Author)
