description With the industry constantly looking into miniaturizing devices, the study of 2D materials and its properties and possible applications has rapidly gained momentum. This final year project (FYP) focuses on the fabrication and characterization of a heterostructure composed of molybdenum disulfide (MoS2), graphene, and hexagonal boron nitride (hBN) for the potential application in light-emitting diodes (LEDs). It delves into the properties of each of these materials to help determine its value in a possible heterostructure for LEDs. The heterostructure was synthesized using mechanical exfoliation and PDMS-assisted transfer techniques, followed by thorough structural and optical characterization.
