Defect Engineering of Two‐Dimensional Molybdenum Disulfide

Chemistry – A European Journal, 2020
AbstractTwo‐dimensional (2D) molybdenum disulfide (MoS2) holds great promise in electronic and optoelectronic applications owing to its unique structure and intriguing properties. The intrinsic defects such as sulfur vacancies (SVs) of MoS2 nanosheets are found to be detrimental to the device efficiency.

Defect engineering using crystal symmetry [PDF]

Proceedings of the National Academy of Sciences, 2018
Defects in solids can be broadly classified based on their dimensionality (1). Zero-dimensional defects (point defects) arise as a consequence of entropy considerations (configurational entropy) and thus are thermodynamically required in any material. One-dimensional defects such as dislocations are not required by thermodynamics but arise anyway as a ...
