Abstract

X-ray diffraction (XRD) and transient charge technique (TCT) were applied to study the lattice parameters and the electronic properties of mercuric iodide (HgI2) crystals doped with hydrocarbons (HC) and excess of iodine or mercury. The lattice spacing along the c-axis is strongly influenced by HCs doping, and expansion of up to 4% has been measured. Smaller changes of lattice parameters have been measured on crystals with iodine or mercury excess. It is suggested that the incorporation of HCs into HgI2 lattice occurs mainly by intercalation, where excess of mercury or iodine are incorporated as interstitials or as vacancy-type defects which induce more traps for charge carriers as reflected by shorter trapping times.
