    by Microspacing Air-Gap Sublimation

## Description

- description: Extended two-dimensional (2D) crystals of dye molecules adsorbed on
    2D material substrates such as boron nitride have recently become a subject of
    intense study, with potential applications ranging from quantum technology to
    optoelectronics. The most established technique for the production of these films
    is physical vapor transport in a vacuum. We demonstrate that few-layer crystalline
    films of the organic dye molecule perylenetetracarboxylic diimide (PTCDI) on boron
    nitride can be produced by microspacing in-air sublimation, a radically simplified
    technique that does not require complicated vacuum systems. The resulting layers
    display clearly resolved atomic step terraces in atomic force microscopy and a
    clear polarization anisotropy in their fluorescence, confirming molecular alignment
    and long-range order. Using density functional theory and classical molecular
    dynamics simulations, the canted motif is identified as the most likely building
    block for the morphology of a PTDCI monolayer on the hBN substrate.
