title: Electrohydrodynamic printing for scalable MoS2 flake coating: application to gas sensing device.
abstract: Scalable sub-micrometer molybdenum disulfide ([Formula: see text]) flake films with highly uniform coverage were created using a systematic approach. An electrohydrodynamic (EHD) printing process realized a remarkably uniform distribution of exfoliated [Formula: see text] flakes on desired substrates. In combination with a fast evaporating dispersion medium and an optimal choice of operating parameters, the EHD printing can produce a film rapidly on a substrate without excessive agglomeration or cluster formation, which can be problems in previously reported liquid-based continuous film methods. The printing of exfoliated [Formula: see text] flakes enabled the fabrication of a gas sensor with high performance and reproducibility for [Formula: see text] and [Formula: see text].
