Synthesis od 2-D materials and spin hybrids
Synthesis by chemical vapour deposition (CVD)
CVD is a fundamental tool used in almost every manufacturing realm: for examples sunglasses to today’s electronic. After the introduction of Graphane, 2D materials are getting boom owing to the potential to advance and replace current silicon based electronic. Layer transition metal dichalcogenides (TMDs), which are mostly MX2 compounds having central metallic atoms (M= W, Mo, Nb,Ta..) sandwiched between two atom layers (X=S,Se,Te..), open up a new way to fabricate wide range of compounds : for example- insulators, semiconductor, metallic, semi-metallic and also superconductor.
We fabricate systematically wide range of materials using CVD technique for instant: single layer, vertical hetero-structure, horizontal hetero-structure, alloy of TMD and these structures are crucial for the purpose of future electronic as well as optoelectronic. Twisting, bending, stacking of TMD helps to create materials with unique properties which generally do not exist naturally. Recently, realization of 2D magnetic materials stimulate key interest especially for spintronic and information processing techniques. In our lab, we fabricate and characterize almost all possible compounds with CVD technique.
