Cadmium Diiodide (CdI2)

Description

Description CdI2 is a layered semiconductor with an indirect gap at 3.0 eV for bulk and its properties in the monolayer form is currently unknown. It crystallizes in generally known as CdI2 crystal structure. The repeating I-Cd-I trilayer stack couples to each other via weak Van der Waals forces. CdI2 crystal can easily be exfoliated down to monolayer using conventional exfoliation techniques.

Features And Benefits

Features And Benefits Material has been developed to achieve impressive purity (99.9995%). Stoichiometry (perfect 1:2 ratio), defect density (less than one point defect for every 75,000 atoms), and single domain size (~90 microns) allowing to exfoliate large monolayers.

Application

Application Energy storage, catalysis, analytical chemistry, mechanics, adsorption, biology, microelectronics, sensors, etc.
