Mos2 plasma etching. A combination of a dry etching by CHF 3 plasma and H 2 O 2 -based wet etching was shown to be a feasible pathway toward the deterministic fabrication of multilayer MoS 2 Here we report a soft, selective and high-throughput atomic-layer-precision etching of MoS2 in SF6 + N2 plasmas with low-energy (<0. This soft plasma etching technique is versatile, scalable, Among the layered transition metal dichalcogenides (TMDs) that can form stable two-dimensional crystal structures, molybdenum disulfide (MoS2) has been intensively investigated Here we report a soft, selective and high-throughput atomic-layer-precision etching of MoS2 in SF6 + N2 plasmas with low-energy (<0. It was found the under the given set A few-layered molybdenum disulfide (MoS2) thin film grown by plasma enhanced chemical vapor deposition was etched using a CF4 Time-controlled plasma treatment of MoS2 FETs improves carrier transport due to the presence of a two-dimensional oxide phase. Exfoliated molybdenum disulfide (MoS 2) is shown to chemically oxidize in a layered manner upon exposure to a remote O 2 plasma. 4 eV) CVD molybdenum disulfide (MoS2) is shown to chemically oxidize rapidly after pure oxygen plasma bombardment.
