Two-dimensional monolayer transition metal dichalcogenides (TMDs) exhibit strong exciton binding energy due to Coulomb interactions, making exciton dissociation challenging. However, the use of orbital angular momentum (OAM) light, or twisted light, enables momentum-conserving transitions, potentially enhancing exciton dissociation and improving optoelectronic performance. In this work, we simultaneously explore the optical and electrical characteristics of a field-effect transistor (FET) fabricated from molybdenum disulfide (MoS
