## Description

- description: Hexagonal-boron-nitride single crystals grown by high-pressure, high-temperature
    (HPHT) synthesis are commonly used as the insulated substrate dielectric for two-dimensional
    (2D) atomic-layered materials like graphene and transition metal dichalcogenides
    (TMDs) to improve the flatness of the 2D materials atomically without disturbing
    the 2D electronic characteristics. However, HPHT single crystals often contain
    impure regions, which can hold subtle clues in regard to the 2D atomic layered
    materials for new discoveries in the physics of 2D materials. To identify the
    position of the impure domains and to avoid them when the 2D devices are prepared,
    a far-UV photoluminescence microscope was developed. This microscope makes it
    possible to visualize the impure growth region with ease in a no-contact and non-destructive
    manner.
