Although the average crystal structure in CuInSnS4 is cubic, phonons and excitons sense disorder in different ways. Left: Phonon modes remain consistent with the cubic structure. Right: In contrast, localized excitons are sensitive to local symmetry breaking associated with cation disorder and exhibit a pronounced anisotropic excitonic response.

Disorder creates new properties in compound semiconductors

An international research team has demonstrated that the intrinsic disorder of the compound semiconductor CuInSnS₄ can be exploited to influence its optical properties. While the atomic vibrations also sense the local disorder, their response is averaged over many different local environments and therefore appear isotropic, as expected for a cubic crystal. In contrast, the optical excitations, known as excitons, are much more sensitive to the local arrangement of atoms. Surpr

An image of the Janus formation reaction in which the outermost chalcogen atom in an atomic layer material is replaced by another chalcogen atom with the support of electron accumulation.

Electron accumulation unlocks room-temperature synthesis of Janus 2D semiconductors

Researchers at Tohoku University have uncovered the long-standing mystery behind the synthesis of Janus two-dimensional (2D) semiconductors, paving the way for more precise manufacturing of materials used in future electronics and clean energy technologies. Janus 2D materials are named after the two-faced Roman god because their top and bottom surfaces are composed of different elements. This asymmetry creates a strong internal electric field, making them attractive for appl
