Summary: Understanding the optothermal physics of quantum materials will enable the efficient design of next-generation photonic and superconducting circuits.Anharmonic phonon dynamics is central to strongly interacting optothermal physics.This is because Swirl Decorations the pressure of a gas of anharmonic phonons is temperature dependent.Phonon-phonon and electron-phonon quantum interactions contribute to the anharmonic phonon effect.
Here we have studied the optothermal properties of physically exfoliated WS2 van der Waals crystal via temperature-dependent Raman spectroscopy and machine learning strategies.This fundamental investigation will lead to unveiling the dependence of temperature on in-plane and out-of-plane Raman ponchos shifts (Raman thermometry) of WS2 to study the thermal conductivity, hot copyright diffusion coefficient, and thermal expansion coefficient.
