Abstract

A method of making a low-dimensional material chemical vapor sensor comprising exfoliating MoS, applying the monolayer flakes of MoSonto a SiO/Si wafer, applying a methylmethacrylate (MMA)/polymethylmethacrylate (PMMA) film, defining trenches for the deposition of metal contacts, and depositing one of Ti/Au, Au, and Pt in the trench and resulting in a MoSsensor. A low-dimensional material chemical vapor sensor comprising monolayer flakes of MoS, trenches in the SiO/Si wafer, metal contacts in the trenches, and thereby resulting in a MoSsensor. A full spectrum sensing suite comprising similarly fabricated parallel sensors made from a variety of low-dimensional materials including graphene, carbon nanotubes, MoS, BN, and the family of transition metal dichalcogenides. The sensing suites are small, robust, sensitive, low-power, inexpensive, and fast in their response to chemical vapor analytes.
