A novel nET-Raman technique is developed to distinguish and characterize these two properties by constructing steady and transient states of different laser heating and Raman probing sizes.. The nET-Raman uses a nanosecond pulsed laser and a continuous wave laser for exciting Raman signals and heating samples. k is found to increase from 15:1þ0:3 0:4 to 38:8 þ2:6 2:4 W$m 1 K 1 when the sample's thickness increases from 13 to 107 nm.

Article Snippet: Steady state Raman spectroscopy is the most widely used opto-thermal technique for measuring a 2D atomic-layer material’s thermal conductivity.. It requires the calibration of temperature coefficients of Raman properties and measurement/calculation of the absolution laser absorption in 2D materials.. Such a requirement is very laborious and introduces very large measurement errors (of the order of 100%) and hinders gaining a precise and deep understanding of phonon–structure interactions in 2D materials.

A new Raman probing technique, frequency-domain energy transport stateresolved Raman (FET-Raman), is developed to resolve these issues and improve the measurement precision significantly.. The FET-Raman uses a steady-state laser and an amplitude-modulated square wave laser for heating the material and simultaneous exciting Raman signals. Article Title: The hot carrier diffusion coefficient of sub-10 nm virgin MoS 2 : uncovered by non-contact optical probing. Article Snippet: We report a novel approach for non-contact simultaneous determination of hot carrier diffusion coefficient (D) and interface thermal resistance (R) of sub-10 nm virgin mechanically exfoliated MoS2 nanosheets on c-Si.. The effect of hot carrier diffusion in heat conduction by photon excitation, diffusion, and recombination is identified by varying the heating spot size from 0.294 μm to 1.14 μm (radius) and probing the local temperature rise using Raman spectroscopy.. R is determined as 4.46~7.66×10 K·m/W, indicating excellent contact between MoS2 and c-Si. |
