Electronic Transport Properties

Molybdenum diselenide belong to the large family of layered transition metal dichalcogenides. It consists of weakly coupled sandwiched layers i.e. Se – Mo – Se in which a Mo atom layer is enclosed within two Se layers. Most TMDCs form hexagonal layered structures. The repeating 2-D unit is a block formed by a plane of M atoms, in between two planes of chalcogen X. Interactions between atoms in a block are mainly covalent, while only saturated orbitals of the chalcogens are exposed to the exterior. Block-to-block interactions are 1 to 2 orders of magnitude weaker than within a block. This structure makes MoSe2 extremely anisotropic in character and leads to unusual structural properties. Studies show that these materials exhibit varieties of properties due to their structure. Therefore study of these materials has received considerable attention because of the great diversity in their physical and electronic properties. In addition, MoSe2 possess flexible nature along with good carrier mobility to make them potential candidate for fabricating flexible high mobility electronic devices such as Schottky barrier devices, FETs, solar cell etc. This book is concerned with an experiment
