CdI₂ is a layered semiconductor with 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 as show

Chromium bromide (CrBr3) is a 2D ferromagnetic semiconductor with a Curie temperature of ~40K. Crystals exhibit perfect 0001 plane orientation as well as perfect in-plane crystallinity as evidenced

CrI3 (chromium triiodide) is a ferromagnetic semiconductor with Curie temperature (Tc) 61 K with significant magnetic anisotropy. Unlike other ferromagnetic vdW crystals the ferromagnetic order

The first and only commercially available Ca(OH)₂ crystals were grown using float zone synthesis technique to yield perfectly layered, large size, highly crystalline vdW layered crystals.

The only commercially available lead iodide (PbI2) by 2Dsemiconductors USA. PbI2 crystallizes in a CdI2 structure, in which I- anions are packed hexagonally

Graphitic carbon nitride (g-C3N4) has been one of the most attractive materials in the field owing to its unique electronic structure. It exhibits 2.7 eV and ideal band alignment to oxidization
