In the common PMMA-mediated transfer method, the etching of the supporting substrate to peel off PMMA/nanomaterial thin-film is usually carried out in hydrofluoric acid or hot potassium hydroxide ...

Graphene consists of a two-dimensional carbon layer in which the carbon atoms are arranged on a hexagonal lattice, resembling a honeycomb. Carbon nanotubes are rolled-up sheets of graphene, and thick ...

The method of fabricating structures and devices at the nanoscale, known as nanofabrication, has resulted in major developments in several fields, such as electronics, medicine, and materials science.

Researchers in Taiwan fabricate high-power red LEDs based on copper substrates. Red LEDs based on a copper substrate can produce a luminous intensity which is three times higher than that of ...

Scientists in the Netherlands have built a perovskite solar cell with a polyamide-imide (PAI) planarization layer to serve as an insulating layer. The device has an open-circuit voltage of 1.11 V, a ...

What is Capillary Force Lithography? Capillary Force Lithography (CFL) is a versatile and cost-effective technique for patterning surfaces at the nanoscale. It leverages the capillary forces arising ...

When an azobenzene-containing polymer film is exposed to non-uniform illumination, a light-induced mass migration process may be induced, leading to the formation of relief patterns on the ...

Polymers are extensively used throughout industry, whether as naturally occurring materials like starch and cellulose, or synthetic commodities like nylon, polystyrene and polyethylene. Polymer ...

Organic semiconductors (OSCs) are promising advanced materials due to their numerous attractive properties, such as their processability (low-temperature processing, low-cost production) and their ...
