Abstract Ternary inverters offer a promising solution to enhance information processing density and efficiency while reducing system complexity, addressing energy limitations in complementary metal‐oxide‐semiconductor technology the post‐Moore era. Among these, standard ternary inverter (STI) is particularly appealing due its symmetry reliability logic operations, though fabrication remains challenging. Here, controllable process‐compatible doping technique reported that combines rapid thermal annealing with h‐BN‐assisted ultraviolet photoinduced achieve area‐selective p‐type n‐type on single MoTe 2 flake. This approach enables of high‐performance anti‐ambipolar transistors (AATs) unipolar field‐effect (FETs) based homojunctions. By achieving near‐perfect conductance matching between connected AATs FETs, an STI highly uniform staircase transfer characteristic intermediate state width precisely one‐third input voltage range demonstrated. The also exhibit peak‐to‐valley ratio exceeding 10 3 , transconductance reversal, tunable peak positions, enabling development frequency doublers without additional bias. study presents novel strategy for efficient multifunctional device fabrication, advancing next‐generation electronic technologies.

Recently, a step-flow growth mode has been proposed to break the inherent molybdenum disulfide (MoS2) crystal domain bimodality and yield single-crystalline MoS2 monolayer on commonly employed sapphire substrates. This work reveals an alternative mechanism during metal–organic chemical vapor deposition (MOCVD) of through anisotropic 2D growth. During early stages, epitaxial symmetry commensurability terraces rather than step inclination ultimately govern orientation. Strikingly, as crystals continue grow laterally, steps transform geometry into diamond-shaped domains presumably by diffusion ad-species facet development. Even though these nucleate with predominantly bimodal 0 60° azimuthal rotation, individual reach lateral dimensions up 200 nm before merging seamlessly upon coalescence.
