Abstract

Two-dimensional (2D) materials are ultra-thin (<5 atoms thick) layers that are currently the subjects of many research studies and publications due to their unique chemical and physical properties. Molybdenum disulfide (MoS2), like other transition metal dichalcogenides (TMDs), have different electronic and optical properties compared to bulk materials with the same composition. These new properties, which include mechanical flexibility and enhanced responses to incident radiation over a broad spectral range arising from reduced dimensionality are the focus of our work.In this proposal, we utilize a new method to rapidly fabricate terahertz (THz) sensors using 2D MoO2. By using a laser annealing system with an automated, programmable stage to directly write patterns of material with the desired electronic properties, THz sensors with different patterns can be easily fabricated in the flexible and low-cost precursor material. This approach provides an inexpensive and rapid approach for fabrication of THz sensors with no masking or photolithography steps and allows our team to correlate experimental measurements of sensor performance to computational simulation results to better understand fundamental theory of THz sensing mechanisms.
