## Description

- description: Second harmonic generation (SHG) is a prominent branch of non-linear
    optics (NLO) heavily reliant on conventional bulk NLO crystals. However, the difficulty
    in downsizing these crystals imposes technical limitations on the future of miniaturized
    NLO devices. Tellurene emerges as a promising candidate to overcome these restrictions,
    excelling in electrical applications and believed to possess a giant second-order
    optical susceptibility comparable to conventional NLO crystals. In this study,
    a face-to-face substrate configuration is employed for the synthesis of ultrathin
    tellurene via PVD. Our findings reveal that tellurene's SHG performance surpasses
    that of monolayer transition metal dichalcogenides by two orders of magnitude,
    with maximum efficiency when the flake thickness is between 16 and 20 nm under
    various wavelengths. High sensitivity to thickness variation encourages post-growth
    thinning through hydrogen plasma etching, enabling precise engineering of the
    flake thickness for optimal SHG. This establishes a foundation for controlled
    tellurene thickness, further broadening its potential in diverse applications.
