    • Abstract

       

      Two-dimensionally confined nanomaterials, popularly known as layered materials, are an emerging class of novel nano-sized materials with exotic chemical and physical properties. 2D materials like graphene, MoS$_2$ and WS$_2$ have offered fabrication of smart nano-electronic devices in recent years. However, based on their particular application, their properties have to be tuned for specific purposes. Presently, photoelectronic applications of these materials demand finetuning of their work function for the design of efficient contact materials, field-emission-based devices and high catalytic response in energy evolution reaction. The work function of layered materials can be effectively modulated through defect engineering. Defects generated in these nanomaterials create strain in the crystal structure which in turn change the work function of the materials. In this work, the defect-induced strain-assisted surface electronic response of layered materials has been reviewed.
