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. Raman spectroscopy revealed the
high crystallinity of the heterostructure, indicating minimal light absorption, while
photoluminescence (PL) analysis demonstrated its capability to emit and reflect white light.
Despite some deviations in characterization outputs, the heterostructure exhibits promising
properties for optoelectronic applications. This FYP aims to provide valuable insights and
foundational knowledge that can serve as a basis for future research in this field of 2D material
based optoelectronics. |
