Strong quantum confinement and coulomb interactions induce tightly bound quasiparticles such as excitons and trions in an atomically thin layer of transitional metal dichalcogenides (TMDs). which play a dominant role in determining their intriguing optoelectronic properties. Thus. controlling the excitonic properties is essential for the applications of TMD-based devices. https://fitnessgravesyardes.shop/product-category/handrail-end-cap/
