As the thickness reduces from 9 to 1.4 nm, sheet resistance will increase from 9 to 530 Ω/square. Hence, a noteworthy decrease in sheet resistance of 2D gold flakes can be attributed to the lower ...

The team also hopes the gold mining sandwich technique can be used to create other tricky 2D materials in the future.

By incorporating gold nanoparticles within the electrode, the team significantly reduced its resistance, leading to a substantial improvement in the performance of the 2D semiconductor image sensor.
