MoS₂・WS₂・MoSe₂・WSe₂へのカルコゲン空孔導入: 近年の手法と分類
New strategies for introducing S/Se vacancies in MoS₂, WS₂, MoSe₂, WSe₂
Abstract: In four representative 2D TMD semiconductors (MoS₂, WS₂, MoSe₂, WSe₂), deliberate introduction of chalcogen (S or Se) vacancies can tailor electronic and optical properties. This article surveys recent (2018–2023) techniques for creating such vacancies – via thermal annealing, plasma treatment, irradiation, chemical routes, or non-stoichiometr…
