Simplified Heterostructure Fabrication:

• The technology simplifies the fabrication of heterostructures using two-dimensional materials, such as h-BN and WS₂.

PMMA Coating:

• It involves the application of a PMMA (poly methyl methacrylate) solution to create a film on the substrate, which serves as a crucial step in the process.

Mechanical Exfoliation:

• The invention utilizes mechanical exfoliation, employing adhesive tape, to obtain two-dimensional material flakes.

Substrate Cleaning:

• Successive cleaning of the substrates using acetone, isopropyl alcohol, and deionized water ensures a clean surface for material deposition.

Manual Alignment:

• Precise alignment and positioning of the two-dimensional materials are achieved manually, without the need for expensive micromanipulators, making the process cost-effective and accessible.
