| description | Ever since the discovery of graphene in 2004, there has been a rapid development in
the field of two-dimensional (2D) materials research. The wide availability of 2D
materials has enabled the construction of 2D van der Waals heterostructures, which
has revolutionized society. These heterostructures consist of a variety of properties
that can be manipulated for applications in the energy storage, optoelectronics, and
electronics industries. The original aim of this project was to leverage a motorized
robotic system in the glovebox for assembling 2D van der Waals heterostructures
with various 2D materials. These 2D materials include graphene, hexagonal boron
nitride (hand), black phosphorus (BP), and indium selenide (InSe). However, due to
issues with the glovebox and the time constraint of the project, the experiment was
subsequently conducted under ambient conditions with the use of the regular 2D
materials dry transfer station. The project involved the use of mechanical exfoliation
using the Scotch tape exfoliation method and dry transfer techniques for the
assembly of the 2D heterostructures. Since air-sensitive materials were being used,
thicker layers of flakes for BP and InSe were selected for usage instead. The
principle behind this action was that the protective oxide layer possessed by thicker
flakes safeguards the flakes from further oxidation and contamination. The
heterostructures constructed were then further examined and characterized for the
application of photodetectors. The experiment results proved that there is immense
potential for BP and InSe to perform together in a photodetector. |
