Growth and characterization of HgI2, PbI2 and PbI2:HgI2 layered semiconductors
This paper presents a methodology for the preparation of <FONT FACE="Symbol">a</font>-HgI2 by Physical Vapor Transport and of PbI2 crystals using the Bridgman technique. The results of the growth of HgI2 diluted in PbI2 by the Bridgman technique are shown for the first time, its limit of solubility having been determined at 600 ppm of HgI2 in the PbI2 matrix. Optical absorption, photoluminescence and electrical conductivity measurements show that the crystals prepared are of good crystalline quality
