제목 Highly Stable Modulation of Electrical Properties of Vacancy-containing Few-layer MoS2 via Thiol-based Molecular Functionalization
초록 MoS2 is considered a promising two-dimensional active channel material for future nanoelectronics. However, the development of a facile, reliable, and controllable doping methodology is still critical for extending the applicability of MoS2. Here, we report surface charge transfer doping via thiol-based binding chemistry for modulating the electrical properties of vacancy-containing MoS2 (v-MoS2). Although vacancies present in 2D materials are generally regarded as undesirable components, we show that the electrical properties of MoS2 can be systematically engineered by exploiting the tight-binding between the thiol group and sulfur vacancies and by choosing different functional groups.
