Mid-infrared Assisted THz Phonon Amplification in a 2D Semiconductor for Room Temperature Detection

Anju Sajan, Christopher Sumner, Fumin Huang, Jakob Ziewer, Rohit Chikkaraddy

Mid-infrared light directly amplifies out-of-plane phonons in few-layer MoS2 by more than 80% at room temperature.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

When mid-infrared (MIR) light is introduced, it couples directly to out-of-plane lattice vibrations, leading to room-temperature phonon amplification exceeding 80%.

C2weakest assumption

The mid-infrared light couples directly to vibrational bonds while bypassing electronic excitation pathways, with the observed Raman enhancement arising solely from increased phonon population rather than other optical or thermal effects.

C3one line summary

Mid-infrared light directly amplifies out-of-plane phonons in few-layer MoS2 by over 80% at room temperature with 300x lower power density than visible light, yielding 0.3 nW/sqrt(Hz) noise-equivalent power for MIR detection.
