## Description

- description: Integrated logic circuits using atomically thin, two-dimensional (2D)
    materials offer several potential advantages compared to established silicon technologies
    such as increased transistor density, circuit complexity, and lower energy dis-
    sipation leading to scaling benefits. In this article, a novel approach to achieve
    tunable doping in 2D semiconductors is explored to achieve complementary transistors
    and logic integration. By selectively transferring WSe2 onto hBN and SiO2 substrates,
    complementary transistor behavior (n- and p-type) was achieved using a UV light
    source and electrostatic activation. Furthermore, advanced characterization techniques,
    including high-resolution transmission electron microscopy (HRTEM) and Kelvin
    probe force microscopy (KPFM), provided insights into the chemical composition
    and surface potential changes after UV writing. Finally, a logic inverter was
    successfully implemented using selectively photo-induced doped WSe2 transistors,
    showcasing the potential for practical logic applications. This innovative method
    opens new avenues for designing energy-efficient and reconfigurable 2D semiconductor
    circuits, addressing key challenges in modern electronics.
