| Abstract | Recent experiments have realized steady-state electrical injection of interlayer excitons in electron-hole bilayers subject to a large bias voltage. In the ideal case in which interlayer tunneling is negligibly weak, the system is in quasi-equilibrium with a reduced effective band gap. Interlayer tunneling introduces a current and drives the system out of equilibrium. In this work we derive a nonequilibrium field theory description of interlayer excitons in biased electron-hole bilayers. In the large bias limit, we find that p-wave interlayer tunneling reduces the effective band gap and increases the effective temperature for intervalley excitons. We discuss possible experimental implications for InAs/GaSb quantum wells and transition metal dichalcogenide bilayers. |

interlayer excitons in electron-hole bilayers subject to a large bias voltage.
In the ideal case in which interlayer tunneling is negligibly weak, the system
is in quasi-equilibrium with a reduced effective band gap. Interlayer tunneling
introduces a current and drives the system out of equilibrium. In this work we
derive a nonequilibrium field theory description of interlayer excitons in
biased electron-hole bilayers. In the large bias limit, we find that p-wave
interlayer tunneling reduces the effective band gap and increases the effective
temperature for intervalley excitons. We discuss possible experimental
implications for InAs/GaSb quantum wells and transition metal dichalcogenide
bilayers. Recent experiments have realized steady-state electrical injection of interlayer excitons in electron-hole bilayers subject to a large bias voltage. In the ideal case in which interlayer tunneling is negligibly weak, the system is in quasi-equilibrium with a reduced effective band gap.
