2D layered transition metal dichalcogenides (LTMDs) attracted a great deal of interests because of their attractive electronic, optoelectronic and mechanical properties, versatile chemistry, and large natural abundance. Especially, a single semiconducting LTMD (e.g., WSe 2 , WS 2 , and MoS 2) layer (~0.5 nm thick) can absorb as much sunlight as 50 nm of Si (or 12 nm of GaAs) and generate curren...

The directed self-assembly (DSA) of block copolymers (BCPs) is a powerful method for the manufacture high-resolution features. Critical issues remain to be addressed successful implementation DSA, such as dewetting and controlled orientation BCP domains through physicochemical manipulations at interfaces, spatial positioning registration Here, we introduce novel top-coat (TC) materials designed...

Advances in roll-to-roll processing of graphene and carbon nanotubes have at last led to the continuous production of high-quality coatings and filaments, ushering in a wave of applications for flexible and wearable electronics, woven fabrics, and wires. These applications often require specific electrical properties, and hence precise control over material micro- and nanostructure. While such ...

The wear of atomic force microscope (AFM) tips is a critical issue in the performance of probe-based metrology and nanomanufacturing processes. In this work, diamond-like carbon (DLC) was coated on Si AFM tips using a plasma ion implantation and deposition process. The mechanical integrity of these DLC-coated tips was compared to that of uncoated silicon tips through systematic nanoscale wear t...

We have successfully fabricated and characterized highly uniform nanopatterned graphene (NPG). Thin anodized aluminum oxide nanomask was prepared by facile self-assembly technique without using polymer buffer layer, which was utilized as a direct-contact template for oxygen plasma etch to produce near-periodic, small-neck-width NPG. The NPG exhibits a homogeneous mesh structure with an average ...
