Enhanced Energy Transfer in Cavity QED Based Phototransistors
We leveraged strong light-matter coupling, a quantum process generating hybridized states, to prepare phototransistors using donor-acceptor pairs that transfer energy via Rabi oscillations. In a prototype experiment, we used a cyanine J-aggregate (TDBC; donor) and MoS<sub>2</sub> monolayer (acceptor) in a field effect transistor cavity to study photoresponsivity. Energy migrates through the newly formed polaritonic ladder, with enhanced device efficiency when the cavity is resonant with donors. A theoretical model based on the time-dependent Schrödinger equation helped interpret results, with polaritonic states acting as a strong energy funnel to the MoS<sub>2</sub> monolayer. These findings suggest novel applications of strong light-matter coupling in quantum materials.
