Low-threshold exciton transport and control in atomically thin semiconductors
Hyeongwoo Lee, Yeonjeong Koo, Jinseong Choi +9
Understanding and controlling the nanoscale transport of excitonic quasiparticles in atomically thin 2D semiconductors is crucial to produce highly efficient nano-excitonic devices…
Tip-induced nano-engineering of strain, bandgap, and exciton dynamics in 2D semiconductors
Yeonjeong Koo, Yongchul Kim, Soo Ho Choi +8
The tunability of the bandgap, absorption and emission energies, photoluminescence (PL) quantum yield, exciton transport, and energy transfer in transition metal dichalcogenide (TM…
Substitutional VSn nanodispersed in MoS film for Pt-scalable catalyst
Frederick Osei-Tutu Agyapong-Fordjour, Seok Joon Yun, Hyung-Jin Kim +10
Among transition metal dichalcogenides (TMdCs) as alternatives for Pt-based catalysts, metallic-TMdCs catalysts have highly reactive basal-plane but are unstable. Meanwhile, chemic…
Chemical reactivity imprint lithography on graphene: Controlling the substrate influence on electron transfer reactions
Qing Hua Wang, Zhong Jin, Ki Kang Kim +10
The chemical functionalization of graphene enables control over electronic properties and sensor recognition sites. However, its study is confounded by an unusually strong influenc…
Delay Analysis of Graphene Field-Effect Transistors
Han Wang, Allen Hsu, Dong Seup Lee +3
In this letter, we analyze the carrier transit delay in graphene field-effect transistors (GFETs). GFETs are fabricated at the wafer-scale on sapphire substrate. For a device with…
