A moiré pattern appears when you stack and rotate two copies of an image with regularly repeating shapes, turning simple patterns of squares or triangles into a groovy wave pattern that moves across ...

Excitons, bound states between an electron (i.e., a negatively charged particle) and a hole (i.e., the absence of an electron) in materials, are a key focus of condensed matter physics studies. These ...

Since the discovery of excitonic resonances in MoS 2 1,2, transition metal dichalcogenides (TMDs) have emerged as a promising platform for applications in classic and quantum technology. The ...

Moiré superlattices have proven to be an exceptionally rich material platform in which different phases of matter can be realized by engineering electronic bands via changing the twist angle, with ...

Researchers capture exciton movement inside single CuPc nanofibers and show how molecular packing and defects shape energy transport in organic semiconductors. (Nanowerk News) Organic semiconductors ...

Two-dimensional (2D) materials have proved to be a promising platform for studying exotic quasiparticles, such as excitons. Excitons are bound states that emerge when an electron in a material absorbs ...
